Steps to Calculate GCD of 189, 764, 277, 456 using LCM Formula

Given numbers are 189, 764, 277, 456

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

Apply this formula for all numbers.

Step1:

LCM(189, 764) = 144396

GCD(189, 764) = ( 189 x 764 ) / 144396

= 189 / 764

= 189


Step2:

LCM(1, 277) = 277

GCD(1, 277) = ( 1 x 277 ) / 277

= 1 / 277

= 1


Step3:

LCM(1, 456) = 456

GCD(1, 456) = ( 1 x 456 ) / 456

= 1 / 456

= 1


So, Greatest Common Divisor of 189, 764, 277, 456 is 1
