Given numbers are 218, 478, 691, 444
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, 691) = 1382
GCD(2, 691) = ( 2 x 691 ) / 1382
= 2 / 691
= 2
Step3:
LCM(1, 444) = 444
GCD(1, 444) = ( 1 x 444 ) / 444
= 1 / 444
= 1
So, Greatest Common Divisor of 218, 478, 691, 444 is 1
