Given numbers are 642, 141, 421, 995

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

Apply this formula for all numbers.

Step1:

LCM(642, 141) = 30174

GCD(642, 141) = ( 642 x 141 ) / 30174

= 642 / 141

= 642

Step2:

LCM(3, 421) = 1263

GCD(3, 421) = ( 3 x 421 ) / 1263

= 3 / 421

= 3

Step3:

LCM(1, 995) = 995

GCD(1, 995) = ( 1 x 995 ) / 995

= 1 / 995

= 1

So, Greatest Common Divisor of 642, 141, 421, 995 is 1
