Given numbers are 642, 454, 744, 219
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(642, 454) = 145734
GCD(642, 454) = ( 642 x 454 ) / 145734
= 642 / 454
= 642
Step2:
LCM(2, 744) = 744
GCD(2, 744) = ( 2 x 744 ) / 744
= 2 / 744
= 2
Step3:
LCM(2, 219) = 438
GCD(2, 219) = ( 2 x 219 ) / 438
= 2 / 219
= 2
So, Greatest Common Divisor of 642, 454, 744, 219 is 1
