Given numbers are 921, 566, 637, 890
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(921, 566) = 521286
GCD(921, 566) = ( 921 x 566 ) / 521286
= 921 / 566
= 921
Step2:
LCM(1, 637) = 637
GCD(1, 637) = ( 1 x 637 ) / 637
= 1 / 637
= 1
Step3:
LCM(1, 890) = 890
GCD(1, 890) = ( 1 x 890 ) / 890
= 1 / 890
= 1
So, Greatest Common Divisor of 921, 566, 637, 890 is 1
