Steps to Calculate GCD of 784, 485, 279, 492 using LCM Formula

Given numbers are 784, 485, 279, 492

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

Apply this formula for all numbers.

Step1:

LCM(784, 485) = 380240

GCD(784, 485) = ( 784 x 485 ) / 380240

= 784 / 485

= 784


Step2:

LCM(1, 279) = 279

GCD(1, 279) = ( 1 x 279 ) / 279

= 1 / 279

= 1


Step3:

LCM(1, 492) = 492

GCD(1, 492) = ( 1 x 492 ) / 492

= 1 / 492

= 1


So, Greatest Common Divisor of 784, 485, 279, 492 is 1
