Given numbers are 642, 102, 724, 705

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

Apply this formula for all numbers.

Step1:

LCM(642, 102) = 10914

GCD(642, 102) = ( 642 x 102 ) / 10914

= 642 / 102

= 642

Step2:

LCM(6, 724) = 2172

GCD(6, 724) = ( 6 x 724 ) / 2172

= 6 / 724

= 6

Step3:

LCM(2, 705) = 1410

GCD(2, 705) = ( 2 x 705 ) / 1410

= 2 / 705

= 2

So, Greatest Common Divisor of 642, 102, 724, 705 is 1
