Steps to Calculate GCD of 221, 510, 649, 917 using LCM Formula

Given numbers are 221, 510, 649, 917

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

Apply this formula for all numbers.

Step1:

LCM(221, 510) = 6630

GCD(221, 510) = ( 221 x 510 ) / 6630

= 221 / 510

= 221


Step2:

LCM(17, 649) = 11033

GCD(17, 649) = ( 17 x 649 ) / 11033

= 17 / 649

= 17


Step3:

LCM(1, 917) = 917

GCD(1, 917) = ( 1 x 917 ) / 917

= 1 / 917

= 1


So, Greatest Common Divisor of 221, 510, 649, 917 is 1
