GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(830, 188) = 78020
GCD(830, 188) = ( 830 x 188 ) / 78020
= 830 / 188
= 830
Step2:
LCM(2, 812) = 812
GCD(2, 812) = ( 2 x 812 ) / 812
= 2 / 812
= 2
Step3:
LCM(2, 286) = 286
GCD(2, 286) = ( 2 x 286 ) / 286
= 2 / 286
= 2
So, Greatest Common Divisor of 830, 188, 812, 286 is 2
