Given numbers are 454, 420, 557, 223
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(454, 420) = 95340
GCD(454, 420) = ( 454 x 420 ) / 95340
= 454 / 420
= 454
Step2:
LCM(2, 557) = 1114
GCD(2, 557) = ( 2 x 557 ) / 1114
= 2 / 557
= 2
Step3:
LCM(1, 223) = 223
GCD(1, 223) = ( 1 x 223 ) / 223
= 1 / 223
= 1
So, Greatest Common Divisor of 454, 420, 557, 223 is 1
