GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(830, 858) = 356070
GCD(830, 858) = ( 830 x 858 ) / 356070
= 830 / 858
= 830
Step2:
LCM(2, 248) = 248
GCD(2, 248) = ( 2 x 248 ) / 248
= 2 / 248
= 2
Step3:
LCM(2, 172) = 172
GCD(2, 172) = ( 2 x 172 ) / 172
= 2 / 172
= 2
So, Greatest Common Divisor of 830, 858, 248, 172 is 2
