Given numbers are 207, 665, 56, 858

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

Apply this formula for all numbers.

Step1:

LCM(207, 665) = 137655

GCD(207, 665) = ( 207 x 665 ) / 137655

= 207 / 665

= 207

Step2:

LCM(1, 56) = 56

GCD(1, 56) = ( 1 x 56 ) / 56

= 1 / 56

= 1

Step3:

LCM(1, 858) = 858

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

= 1 / 858

= 1

So, Greatest Common Divisor of 207, 665, 56, 858 is 1
