Given numbers are 777, 672, 491, 909
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(777, 672) = 24864
GCD(777, 672) = ( 777 x 672 ) / 24864
= 777 / 672
= 777
Step2:
LCM(21, 491) = 10311
GCD(21, 491) = ( 21 x 491 ) / 10311
= 21 / 491
= 21
Step3:
LCM(1, 909) = 909
GCD(1, 909) = ( 1 x 909 ) / 909
= 1 / 909
= 1
So, Greatest Common Divisor of 777, 672, 491, 909 is 1
