Steps to Calculate GCD of 550, 774, 516, 621 using LCM Formula

Given numbers are 550, 774, 516, 621

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

Apply this formula for all numbers.

Step1:

LCM(550, 774) = 212850

GCD(550, 774) = ( 550 x 774 ) / 212850

= 550 / 774

= 550


Step2:

LCM(2, 516) = 516

GCD(2, 516) = ( 2 x 516 ) / 516

= 2 / 516

= 2


Step3:

LCM(2, 621) = 1242

GCD(2, 621) = ( 2 x 621 ) / 1242

= 2 / 621

= 2


So, Greatest Common Divisor of 550, 774, 516, 621 is 1
