Given numbers are 281, 147, 858, 387

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

Apply this formula for all numbers.

Step1:

LCM(281, 147) = 41307

GCD(281, 147) = ( 281 x 147 ) / 41307

= 281 / 147

= 281

Step2:

LCM(1, 858) = 858

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

= 1 / 858

= 1

Step3:

LCM(1, 387) = 387

GCD(1, 387) = ( 1 x 387 ) / 387

= 1 / 387

= 1

So, Greatest Common Divisor of 281, 147, 858, 387 is 1
