Given numbers are 286, 621, 921, 521
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(286, 621) = 177606
GCD(286, 621) = ( 286 x 621 ) / 177606
= 286 / 621
= 286
Step2:
LCM(1, 921) = 921
GCD(1, 921) = ( 1 x 921 ) / 921
= 1 / 921
= 1
Step3:
LCM(1, 521) = 521
GCD(1, 521) = ( 1 x 521 ) / 521
= 1 / 521
= 1
So, Greatest Common Divisor of 286, 621, 921, 521 is 1
