Given numbers are 830, 129, 920

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

Apply this formula for all numbers.

Step1:

LCM(830, 129) = 107070

GCD(830, 129) = ( 830 x 129 ) / 107070

= 830 / 129

= 830

Step2:

LCM(1, 920) = 920

GCD(1, 920) = ( 1 x 920 ) / 920

= 1 / 920

= 1

So, Greatest Common Divisor of 830, 129, 920 is 1
