Steps to Calculate GCD of 649, 301, 617, 221 using LCM Formula

Given numbers are 649, 301, 617, 221

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

Apply this formula for all numbers.

Step1:

LCM(649, 301) = 195349

GCD(649, 301) = ( 649 x 301 ) / 195349

= 649 / 301

= 649


Step2:

LCM(1, 617) = 617

GCD(1, 617) = ( 1 x 617 ) / 617

= 1 / 617

= 1


Step3:

LCM(1, 221) = 221

GCD(1, 221) = ( 1 x 221 ) / 221

= 1 / 221

= 1


So, Greatest Common Divisor of 649, 301, 617, 221 is 1
