Given numbers are 620, 132, 438, 918

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

Apply this formula for all numbers.

Step1:

LCM(620, 132) = 20460

GCD(620, 132) = ( 620 x 132 ) / 20460

= 620 / 132

= 620

Step2:

LCM(4, 438) = 876

GCD(4, 438) = ( 4 x 438 ) / 876

= 4 / 438

= 4

Step3:

LCM(2, 918) = 918

GCD(2, 918) = ( 2 x 918 ) / 918

= 2 / 918

= 2

So, Greatest Common Divisor of 620, 132, 438, 918 is 2
