Question

Find hcf and lcm of 25,40,60 using fundamental theorem of arithmetic

Answer 1

Answer:

HCF = 5

LCM = 600

Step-by-step explanation:

Find hcf and lcm of 25,40,60

25 = 5 * 5

40 = 2 * 2* 2 * 5

60 = 2 * 2 * 3 * 5

HCF = Highest Common Factor

5 is the common factor in all

HCF of 25 , 40 & 60  =  5

LCM  = 5 * 5 * 2 * 2 * 2 * 3 = 600

LCM of 25,40,60  = 600

Answer 2

Answer:

Hcf of 25,40,60 =5

lcm of 25,40,60 =600

Step-by-step explanation:

25=5×5

=5^2

40=5×2×2×2

=5×2^3

60=5×2×2×3

=5×2^2×3

HCF= 5 ( see above 5 comes in time in 25,40 and 60)

LCM=5^2×2^3×3 =600
