Steps to Calculate GCD of 784, 423, 840, 312 using LCM Formula

Given numbers are 784, 423, 840, 312

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

Apply this formula for all numbers.

Step1:

LCM(784, 423) = 331632

GCD(784, 423) = ( 784 x 423 ) / 331632

= 784 / 423

= 784


Step2:

LCM(1, 840) = 840

GCD(1, 840) = ( 1 x 840 ) / 840

= 1 / 840

= 1


Step3:

LCM(1, 312) = 312

GCD(1, 312) = ( 1 x 312 ) / 312

= 1 / 312

= 1


So, Greatest Common Divisor of 784, 423, 840, 312 is 1
