Given numbers are 478, 309, 625, 836

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

Apply this formula for all numbers.

Step1:

LCM(478, 309) = 147702

GCD(478, 309) = ( 478 x 309 ) / 147702

= 478 / 309

= 478

Step2:

LCM(1, 625) = 625

GCD(1, 625) = ( 1 x 625 ) / 625

= 1 / 625

= 1

Step3:

LCM(1, 836) = 836

GCD(1, 836) = ( 1 x 836 ) / 836

= 1 / 836

= 1

So, Greatest Common Divisor of 478, 309, 625, 836 is 1
