Given numbers are 921, 402, 840, 227
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(921, 402) = 123414
GCD(921, 402) = ( 921 x 402 ) / 123414
= 921 / 402
= 921
Step2:
LCM(3, 840) = 840
GCD(3, 840) = ( 3 x 840 ) / 840
= 3 / 840
= 3
Step3:
LCM(3, 227) = 681
GCD(3, 227) = ( 3 x 227 ) / 681
= 3 / 227
= 3
So, Greatest Common Divisor of 921, 402, 840, 227 is 1
