Given numbers are 921, 540, 688, 153

The list of prime factors of all numbers are

Prime factors of 921 are 3 x 307

Prime factors of 540 are 2 x 2 x 3 x 3 x 3 x 5

Prime factors of 688 are 2 x 2 x 2 x 2 x 43

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 921, 540, 688, 153

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

Apply this formula for all numbers.

Step1:

LCM(921, 540) = 165780

GCD(921, 540) = ( 921 x 540 ) / 165780

= 921 / 540

= 921

Step2:

LCM(3, 688) = 2064

GCD(3, 688) = ( 3 x 688 ) / 2064

= 3 / 688

= 3

Step3:

LCM(1, 153) = 153

GCD(1, 153) = ( 1 x 153 ) / 153

= 1 / 153

= 1

So, Greatest Common Divisor of 921, 540, 688, 153 is 1
