Given numbers are 644, 412, 615, 482

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

Apply this formula for all numbers.

Step1:

LCM(644, 412) = 66332

GCD(644, 412) = ( 644 x 412 ) / 66332

= 644 / 412

= 644

Step2:

LCM(4, 615) = 2460

GCD(4, 615) = ( 4 x 615 ) / 2460

= 4 / 615

= 4

Step3:

LCM(1, 482) = 482

GCD(1, 482) = ( 1 x 482 ) / 482

= 1 / 482

= 1

So, Greatest Common Divisor of 644, 412, 615, 482 is 1
