Given numbers are 858, 882, 81, 428

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

Apply this formula for all numbers.

Step1:

LCM(858, 882) = 126126

GCD(858, 882) = ( 858 x 882 ) / 126126

= 858 / 882

= 858

Step2:

LCM(6, 81) = 162

GCD(6, 81) = ( 6 x 81 ) / 162

= 6 / 81

= 6

Step3:

LCM(3, 428) = 1284

GCD(3, 428) = ( 3 x 428 ) / 1284

= 3 / 428

= 3

So, Greatest Common Divisor of 858, 882, 81, 428 is 1
