GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(219, 661) = 144759
GCD(219, 661) = ( 219 x 661 ) / 144759
= 219 / 661
= 219
Step2:
LCM(1, 454) = 454
GCD(1, 454) = ( 1 x 454 ) / 454
= 1 / 454
= 1
Step3:
LCM(1, 912) = 912
GCD(1, 912) = ( 1 x 912 ) / 912
= 1 / 912
= 1
So, Greatest Common Divisor of 219, 661, 454, 912 is 1
