Steps to Calculate GCD of 649, 668, 155, 340 using LCM Formula

Given numbers are 649, 668, 155, 340

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

Apply this formula for all numbers.

Step1:

LCM(649, 668) = 433532

GCD(649, 668) = ( 649 x 668 ) / 433532

= 649 / 668

= 649


Step2:

LCM(1, 155) = 155

GCD(1, 155) = ( 1 x 155 ) / 155

= 1 / 155

= 1


Step3:

LCM(1, 340) = 340

GCD(1, 340) = ( 1 x 340 ) / 340

= 1 / 340

= 1


So, Greatest Common Divisor of 649, 668, 155, 340 is 1
