Given numbers are 621, 139, 830

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

Apply this formula for all numbers.

Step1:

LCM(621, 139) = 86319

GCD(621, 139) = ( 621 x 139 ) / 86319

= 621 / 139

= 621

Step2:

LCM(1, 830) = 830

GCD(1, 830) = ( 1 x 830 ) / 830

= 1 / 830

= 1

So, Greatest Common Divisor of 621, 139, 830 is 1
