Given numbers are 621, 331, 130, 777
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(621, 331) = 205551
GCD(621, 331) = ( 621 x 331 ) / 205551
= 621 / 331
= 621
Step2:
LCM(1, 130) = 130
GCD(1, 130) = ( 1 x 130 ) / 130
= 1 / 130
= 1
Step3:
LCM(1, 777) = 777
GCD(1, 777) = ( 1 x 777 ) / 777
= 1 / 777
= 1
So, Greatest Common Divisor of 621, 331, 130, 777 is 1
