Given numbers are 564, 220, 423, 921
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(564, 220) = 31020
GCD(564, 220) = ( 564 x 220 ) / 31020
= 564 / 220
= 564
Step2:
LCM(4, 423) = 1692
GCD(4, 423) = ( 4 x 423 ) / 1692
= 4 / 423
= 4
Step3:
LCM(1, 921) = 921
GCD(1, 921) = ( 1 x 921 ) / 921
= 1 / 921
= 1
So, Greatest Common Divisor of 564, 220, 423, 921 is 1
