Given numbers are 47, 77, 15, 98

The list of prime factors of all numbers are

Prime factors of 47 are 47

Prime factors of 77 are 7 x 11

Prime factors of 15 are 3 x 5

Prime factors of 98 are 2 x 7 x 7

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 47, 77, 15, 98

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(47, 77) = 3619

GCD(47, 77) = ( 47 x 77 ) / 3619

= 47 / 77

= 47

Step2:

LCM(1, 15) = 15

GCD(1, 15) = ( 1 x 15 ) / 15

= 1 / 15

= 1

Step3:

LCM(1, 98) = 98

GCD(1, 98) = ( 1 x 98 ) / 98

= 1 / 98

= 1

So, Greatest Common Divisor of 47, 77, 15, 98 is 1
