Given numbers are 825, 858, 618, 813

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

Apply this formula for all numbers.

Step1:

LCM(825, 858) = 21450

GCD(825, 858) = ( 825 x 858 ) / 21450

= 825 / 858

= 825

Step2:

LCM(33, 618) = 6798

GCD(33, 618) = ( 33 x 618 ) / 6798

= 33 / 618

= 33

Step3:

LCM(3, 813) = 813

GCD(3, 813) = ( 3 x 813 ) / 813

= 3 / 813

= 3

So, Greatest Common Divisor of 825, 858, 618, 813 is 3
