Given numbers are 642, 714, 122, 620

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

Apply this formula for all numbers.

Step1:

LCM(642, 714) = 76398

GCD(642, 714) = ( 642 x 714 ) / 76398

= 642 / 714

= 642

Step2:

LCM(6, 122) = 366

GCD(6, 122) = ( 6 x 122 ) / 366

= 6 / 122

= 6

Step3:

LCM(2, 620) = 620

GCD(2, 620) = ( 2 x 620 ) / 620

= 2 / 620

= 2

So, Greatest Common Divisor of 642, 714, 122, 620 is 2
