Given numbers are 988, 570, 255, 774
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(988, 570) = 14820
GCD(988, 570) = ( 988 x 570 ) / 14820
= 988 / 570
= 988
Step2:
LCM(38, 255) = 9690
GCD(38, 255) = ( 38 x 255 ) / 9690
= 38 / 255
= 38
Step3:
LCM(1, 774) = 774
GCD(1, 774) = ( 1 x 774 ) / 774
= 1 / 774
= 1
So, Greatest Common Divisor of 988, 570, 255, 774 is 1
