Answer:
best way to find
Step I:
Divide the large number by the smaller one.
Step II:
Then the remainder is treated as divisor and the divisor as dividend.
Step III:
Divide the first divisor by the first remainder.
Step IV:
Divide the second divisor by the second remainder.
Step V:
Continue this process till the remainder becomes 0.
Step VI:
The divisor which does not leave a remainder is the H.C.F. or G.C.D. of the two numbers and thus, the last divisor is the required highest common factor (H.C.F) of the given numbers.
and this is your answer
Step-by-step explanation:
1.Greatest common factor (GCF) of 30 and 50 is 10. We will now calculate the prime factors of 30 and 50, than find the greatest common factor (greatest common divisor (gcd) of the numbers by matching the biggest common factor of 30 and 50.
2.Greatest common factor (GCF) of 9 and 24 is 3. We will now calculate the prime factors of 9 and 24, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 9 and 24.
3.The gcf of 28 and 35 can be obtained like this: The factors of 28 are 28, 14, 7, 4, 2, 1. The factors of 35 are 35, 7, 5, 1. The common factors of 28 and 35 are 7, 1, intersecting the two sets above.
4.98=2*7*7
96=2*2*2*2*2*3
HCF=2
5.Highest common factor of 84 and 105 = 3 × 7 = 21. 5. Find highest common factor (HCF) of 124, 296 and 228 by using prime factorization method.
6.Find the prime factorization of 80
80 = 2 × 2 × 2 × 2 × 5
Find the prime factorization of 110
110 = 2 × 5 × 11
To find the GCF, multiply all the prime factors common to both numbers:
Therefore, GCF = 2 × 5
GCF = 10
7.gcf, hcf, gcd (360; 420) = 60 = 2^2 × 3 × 5: greatest (highest) common factor (divisor), calculated. The numbers have common prime factors.
