Given numbers are 621, 428, 227, 977
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(621, 428) = 265788
GCD(621, 428) = ( 621 x 428 ) / 265788
= 621 / 428
= 621
Step2:
LCM(1, 227) = 227
GCD(1, 227) = ( 1 x 227 ) / 227
= 1 / 227
= 1
Step3:
LCM(1, 977) = 977
GCD(1, 977) = ( 1 x 977 ) / 977
= 1 / 977
= 1
So, Greatest Common Divisor of 621, 428, 227, 977 is 1
