Given numbers are 646, 645, 937, 659

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

Apply this formula for all numbers.

Step1:

LCM(646, 645) = 416670

GCD(646, 645) = ( 646 x 645 ) / 416670

= 646 / 645

= 646

Step2:

LCM(1, 937) = 937

GCD(1, 937) = ( 1 x 937 ) / 937

= 1 / 937

= 1

Step3:

LCM(1, 659) = 659

GCD(1, 659) = ( 1 x 659 ) / 659

= 1 / 659

= 1

So, Greatest Common Divisor of 646, 645, 937, 659 is 1
