Given numbers are 630, 858, 862, 811
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(630, 858) = 90090
GCD(630, 858) = ( 630 x 858 ) / 90090
= 630 / 858
= 630
Step2:
LCM(6, 862) = 2586
GCD(6, 862) = ( 6 x 862 ) / 2586
= 6 / 862
= 6
Step3:
LCM(2, 811) = 1622
GCD(2, 811) = ( 2 x 811 ) / 1622
= 2 / 811
= 2
So, Greatest Common Divisor of 630, 858, 862, 811 is 1
