Steps to Calculate GCD of 771, 747, 81, 545 using LCM Formula
Given numbers are 771, 747, 81, 545
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(771, 747) = 191979
GCD(771, 747) = ( 771 x 747 ) / 191979
= 771 / 747
= 771
Step2:
LCM(3, 81) = 81
GCD(3, 81) = ( 3 x 81 ) / 81
= 3 / 81
= 3
Step3:
LCM(3, 545) = 1635
GCD(3, 545) = ( 3 x 545 ) / 1635
= 3 / 545
= 3
So, Greatest Common Divisor of 771, 747, 81, 545 is 1
