Steps to Calculate GCD of 121, 723, 771, 780 using LCM Formula

Given numbers are 121, 723, 771, 780

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(121, 723) = 87483

GCD(121, 723) = ( 121 x 723 ) / 87483

= 121 / 723

= 121


Step2:

LCM(1, 771) = 771

GCD(1, 771) = ( 1 x 771 ) / 771

= 1 / 771

= 1


Step3:

LCM(1, 780) = 780

GCD(1, 780) = ( 1 x 780 ) / 780

= 1 / 780

= 1


So, Greatest Common Divisor of 121, 723, 771, 780 is 1
