Steps to Calculate GCD of 857, 661, 38, 771 using LCM Formula
Given numbers are 857, 661, 38, 771
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(857, 661) = 566477
GCD(857, 661) = ( 857 x 661 ) / 566477
= 857 / 661
= 857
Step2:
LCM(1, 38) = 38
GCD(1, 38) = ( 1 x 38 ) / 38
= 1 / 38
= 1
Step3:
LCM(1, 771) = 771
GCD(1, 771) = ( 1 x 771 ) / 771
= 1 / 771
= 1
So, Greatest Common Divisor of 857, 661, 38, 771 is 1
