Given numbers are 642, 238, 291, 152
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(642, 238) = 76398
GCD(642, 238) = ( 642 x 238 ) / 76398
= 642 / 238
= 642
Step2:
LCM(2, 291) = 582
GCD(2, 291) = ( 2 x 291 ) / 582
= 2 / 291
= 2
Step3:
LCM(1, 152) = 152
GCD(1, 152) = ( 1 x 152 ) / 152
= 1 / 152
= 1
So, Greatest Common Divisor of 642, 238, 291, 152 is 1
