GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(218, 478) = 52102
GCD(218, 478) = ( 218 x 478 ) / 52102
= 218 / 478
= 218
Step2:
LCM(2, 272) = 272
GCD(2, 272) = ( 2 x 272 ) / 272
= 2 / 272
= 2
Step3:
LCM(2, 452) = 452
GCD(2, 452) = ( 2 x 452 ) / 452
= 2 / 452
= 2
So, Greatest Common Divisor of 218, 478, 272, 452 is 2
