Steps to Calculate GCD of 421, 784, 456, 487 using LCM Formula

Given numbers are 421, 784, 456, 487

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

Apply this formula for all numbers.

Step1:

LCM(421, 784) = 330064

GCD(421, 784) = ( 421 x 784 ) / 330064

= 421 / 784

= 421


Step2:

LCM(1, 456) = 456

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

= 1 / 456

= 1


Step3:

LCM(1, 487) = 487

GCD(1, 487) = ( 1 x 487 ) / 487

= 1 / 487

= 1


So, Greatest Common Divisor of 421, 784, 456, 487 is 1
