Given numbers are 647, 542, 658, 956

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

Apply this formula for all numbers.

Step1:

LCM(647, 542) = 350674

GCD(647, 542) = ( 647 x 542 ) / 350674

= 647 / 542

= 647

Step2:

LCM(1, 658) = 658

GCD(1, 658) = ( 1 x 658 ) / 658

= 1 / 658

= 1

Step3:

LCM(1, 956) = 956

GCD(1, 956) = ( 1 x 956 ) / 956

= 1 / 956

= 1

So, Greatest Common Divisor of 647, 542, 658, 956 is 1
