Given numbers are 642, 370, 729, 893

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

Apply this formula for all numbers.

Step1:

LCM(642, 370) = 118770

GCD(642, 370) = ( 642 x 370 ) / 118770

= 642 / 370

= 642

Step2:

LCM(2, 729) = 1458

GCD(2, 729) = ( 2 x 729 ) / 1458

= 2 / 729

= 2

Step3:

LCM(1, 893) = 893

GCD(1, 893) = ( 1 x 893 ) / 893

= 1 / 893

= 1

So, Greatest Common Divisor of 642, 370, 729, 893 is 1
