Steps to Calculate GCD of 408, 392, 819, 157 using LCM Formula

Given numbers are 408, 392, 819, 157

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

Apply this formula for all numbers.

Step1:

LCM(408, 392) = 19992

GCD(408, 392) = ( 408 x 392 ) / 19992

= 408 / 392

= 408


Step2:

LCM(8, 819) = 6552

GCD(8, 819) = ( 8 x 819 ) / 6552

= 8 / 819

= 8


Step3:

LCM(1, 157) = 157

GCD(1, 157) = ( 1 x 157 ) / 157

= 1 / 157

= 1


So, Greatest Common Divisor of 408, 392, 819, 157 is 1
