Given numbers are 647, 640, 957, 122

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

Apply this formula for all numbers.

Step1:

LCM(647, 640) = 414080

GCD(647, 640) = ( 647 x 640 ) / 414080

= 647 / 640

= 647

Step2:

LCM(1, 957) = 957

GCD(1, 957) = ( 1 x 957 ) / 957

= 1 / 957

= 1

Step3:

LCM(1, 122) = 122

GCD(1, 122) = ( 1 x 122 ) / 122

= 1 / 122

= 1

So, Greatest Common Divisor of 647, 640, 957, 122 is 1
