Given numbers are 643, 262, 858, 859

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

Apply this formula for all numbers.

Step1:

LCM(643, 262) = 168466

GCD(643, 262) = ( 643 x 262 ) / 168466

= 643 / 262

= 643

Step2:

LCM(1, 858) = 858

GCD(1, 858) = ( 1 x 858 ) / 858

= 1 / 858

= 1

Step3:

LCM(1, 859) = 859

GCD(1, 859) = ( 1 x 859 ) / 859

= 1 / 859

= 1

So, Greatest Common Divisor of 643, 262, 858, 859 is 1
