Given numbers are 478, 148, 608, 621

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

Apply this formula for all numbers.

Step1:

LCM(478, 148) = 35372

GCD(478, 148) = ( 478 x 148 ) / 35372

= 478 / 148

= 478

Step2:

LCM(2, 608) = 608

GCD(2, 608) = ( 2 x 608 ) / 608

= 2 / 608

= 2

Step3:

LCM(2, 621) = 1242

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

= 2 / 621

= 2

So, Greatest Common Divisor of 478, 148, 608, 621 is 1
