The list of prime factors of all numbers are

Prime factors of 357 are 3 x 7 x 17

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

Prime factors of 644 are 2 x 2 x 7 x 23

Prime factors of 153 are 3 x 3 x 17

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

Given numbers are 357, 980, 644, 153

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

Apply this formula for all numbers.

Step1:

LCM(357, 980) = 49980

GCD(357, 980) = ( 357 x 980 ) / 49980

= 357 / 980

= 357

Step2:

LCM(7, 644) = 644

GCD(7, 644) = ( 7 x 644 ) / 644

= 7 / 644

= 7

Step3:

LCM(7, 153) = 1071

GCD(7, 153) = ( 7 x 153 ) / 1071

= 7 / 153

= 7

So, Greatest Common Divisor of 357, 980, 644, 153 is 1
