Given numbers are 416, 242, 178, 621

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

Apply this formula for all numbers.

Step1:

LCM(416, 242) = 50336

GCD(416, 242) = ( 416 x 242 ) / 50336

= 416 / 242

= 416

Step2:

LCM(2, 178) = 178

GCD(2, 178) = ( 2 x 178 ) / 178

= 2 / 178

= 2

Step3:

LCM(2, 621) = 1242

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

= 2 / 621

= 2

So, Greatest Common Divisor of 416, 242, 178, 621 is 1
