remainder
​

Answer 1

Answer:

15

Step-by-step explanation:

The largest number which divides these three numbers are their hcf

60 = 2×2×3×5

75 = 3×5×5

90 = 2×3×3×5

Hcf = 3×5 = 15

The answer is 15

Answer 2

Answer:15

step-by-step explanation :

first let's find prime factors of 60 75 and 90

60 - 2; 2 ;3; 5.

75- 3;5;2.

90 2;3;2;5.

here highest common power of 2 is 0.

Here highest common power of 3 is 1.

Here highest common power of 5 is 1.

Thus HCF (60, 75, 90)-2 0 3^1*5^1

=1*3*5=15

Thus the greatest number which can divide 60,75 and 90 is 15
