Steps to Calculate GCD of 123, 197, 816, 372 using LCM Formula

Given numbers are 123, 197, 816, 372

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

Apply this formula for all numbers.

Step1:

LCM(123, 197) = 24231

GCD(123, 197) = ( 123 x 197 ) / 24231

= 123 / 197

= 123


Step2:

LCM(1, 816) = 816

GCD(1, 816) = ( 1 x 816 ) / 816

= 1 / 816

= 1


Step3:

LCM(1, 372) = 372

GCD(1, 372) = ( 1 x 372 ) / 372

= 1 / 372

= 1


So, Greatest Common Divisor of 123, 197, 816, 372 is 1
