Given numbers are 777, 686, 413, 680
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(777, 686) = 76146
GCD(777, 686) = ( 777 x 686 ) / 76146
= 777 / 686
= 777
Step2:
LCM(7, 413) = 413
GCD(7, 413) = ( 7 x 413 ) / 413
= 7 / 413
= 7
Step3:
LCM(7, 680) = 4760
GCD(7, 680) = ( 7 x 680 ) / 4760
= 7 / 680
= 7
So, Greatest Common Divisor of 777, 686, 413, 680 is 1
