Given numbers are 977, 161, 402, 756

The list of prime factors of all numbers are

Prime factors of 977 are 977

Prime factors of 161 are 7 x 23

Prime factors of 402 are 2 x 3 x 67

Prime factors of 756 are 2 x 2 x 3 x 3 x 3 x 7

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

Given numbers are 977, 161, 402, 756

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

Apply this formula for all numbers.

Step1:

LCM(977, 161) = 157297

GCD(977, 161) = ( 977 x 161 ) / 157297

= 977 / 161

= 977

Step2:

LCM(1, 402) = 402

GCD(1, 402) = ( 1 x 402 ) / 402

= 1 / 402

= 1

Step3:

LCM(1, 756) = 756

GCD(1, 756) = ( 1 x 756 ) / 756

= 1 / 756

= 1

So, Greatest Common Divisor of 977, 161, 402, 756 is 1
