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
