Given numbers are 436, 767, 665, 980

The list of prime factors of all numbers are

Prime factors of 436 are 2 x 2 x 109

Prime factors of 767 are 13 x 59

Prime factors of 665 are 5 x 7 x 19

Prime factors of 980 are 2 x 2 x 5 x 7 x 7

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

Given numbers are 436, 767, 665, 980

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

Apply this formula for all numbers.

Step1:

LCM(436, 767) = 334412

GCD(436, 767) = ( 436 x 767 ) / 334412

= 436 / 767

= 436

Step2:

LCM(1, 665) = 665

GCD(1, 665) = ( 1 x 665 ) / 665

= 1 / 665

= 1

Step3:

LCM(1, 980) = 980

GCD(1, 980) = ( 1 x 980 ) / 980

= 1 / 980

= 1

So, Greatest Common Divisor of 436, 767, 665, 980 is 1
