Given numbers are 858, 548, 215, 578

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

Apply this formula for all numbers.

Step1:

LCM(858, 548) = 235092

GCD(858, 548) = ( 858 x 548 ) / 235092

= 858 / 548

= 858

Step2:

LCM(2, 215) = 430

GCD(2, 215) = ( 2 x 215 ) / 430

= 2 / 215

= 2

Step3:

LCM(1, 578) = 578

GCD(1, 578) = ( 1 x 578 ) / 578

= 1 / 578

= 1

So, Greatest Common Divisor of 858, 548, 215, 578 is 1
