Given numbers are 858, 390, 977, 178

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

Apply this formula for all numbers.

Step1:

LCM(858, 390) = 4290

GCD(858, 390) = ( 858 x 390 ) / 4290

= 858 / 390

= 858

Step2:

LCM(78, 977) = 76206

GCD(78, 977) = ( 78 x 977 ) / 76206

= 78 / 977

= 78

Step3:

LCM(1, 178) = 178

GCD(1, 178) = ( 1 x 178 ) / 178

= 1 / 178

= 1

So, Greatest Common Divisor of 858, 390, 977, 178 is 1
