Steps to Calculate GCD of 123, 746, 578, 263 using LCM Formula

Given numbers are 123, 746, 578, 263

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

Apply this formula for all numbers.

Step1:

LCM(123, 746) = 91758

GCD(123, 746) = ( 123 x 746 ) / 91758

= 123 / 746

= 123


Step2:

LCM(1, 578) = 578

GCD(1, 578) = ( 1 x 578 ) / 578

= 1 / 578

= 1


Step3:

LCM(1, 263) = 263

GCD(1, 263) = ( 1 x 263 ) / 263

= 1 / 263

= 1


So, Greatest Common Divisor of 123, 746, 578, 263 is 1
