Steps to Calculate GCD of 656, 606, 705, 493 using LCM Formula

Given numbers are 656, 606, 705, 493

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

Apply this formula for all numbers.

Step1:

LCM(656, 606) = 198768

GCD(656, 606) = ( 656 x 606 ) / 198768

= 656 / 606

= 656


Step2:

LCM(2, 705) = 1410

GCD(2, 705) = ( 2 x 705 ) / 1410

= 2 / 705

= 2


Step3:

LCM(1, 493) = 493

GCD(1, 493) = ( 1 x 493 ) / 493

= 1 / 493

= 1


So, Greatest Common Divisor of 656, 606, 705, 493 is 1
