Given numbers are 642, 469, 202, 118

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

Apply this formula for all numbers.

Step1:

LCM(642, 469) = 301098

GCD(642, 469) = ( 642 x 469 ) / 301098

= 642 / 469

= 642

Step2:

LCM(1, 202) = 202

GCD(1, 202) = ( 1 x 202 ) / 202

= 1 / 202

= 1

Step3:

LCM(1, 118) = 118

GCD(1, 118) = ( 1 x 118 ) / 118

= 1 / 118

= 1

So, Greatest Common Divisor of 642, 469, 202, 118 is 1
