Given numbers are 642, 988, 162, 951
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(642, 988) = 317148
GCD(642, 988) = ( 642 x 988 ) / 317148
= 642 / 988
= 642
Step2:
LCM(2, 162) = 162
GCD(2, 162) = ( 2 x 162 ) / 162
= 2 / 162
= 2
Step3:
LCM(2, 951) = 1902
GCD(2, 951) = ( 2 x 951 ) / 1902
= 2 / 951
= 2
So, Greatest Common Divisor of 642, 988, 162, 951 is 1
