Steps to Calculate GCD of 649, 761, 506, 491 using LCM Formula

Given numbers are 649, 761, 506, 491

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

Apply this formula for all numbers.

Step1:

LCM(649, 761) = 493889

GCD(649, 761) = ( 649 x 761 ) / 493889

= 649 / 761

= 649


Step2:

LCM(1, 506) = 506

GCD(1, 506) = ( 1 x 506 ) / 506

= 1 / 506

= 1


Step3:

LCM(1, 491) = 491

GCD(1, 491) = ( 1 x 491 ) / 491

= 1 / 491

= 1
