Given numbers are 642, 818, 942, 659

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

Apply this formula for all numbers.

Step1:

LCM(642, 818) = 262578

GCD(642, 818) = ( 642 x 818 ) / 262578

= 642 / 818

= 642

Step2:

LCM(2, 942) = 942

GCD(2, 942) = ( 2 x 942 ) / 942

= 2 / 942

= 2

Step3:

LCM(2, 659) = 1318

GCD(2, 659) = ( 2 x 659 ) / 1318

= 2 / 659

= 2

So, Greatest Common Divisor of 642, 818, 942, 659 is 1
