Given numbers are 858, 391, 901, 213

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

Apply this formula for all numbers.

Step1:

LCM(858, 391) = 335478

GCD(858, 391) = ( 858 x 391 ) / 335478

= 858 / 391

= 858

Step2:

LCM(1, 901) = 901

GCD(1, 901) = ( 1 x 901 ) / 901

= 1 / 901

= 1

Step3:

LCM(1, 213) = 213

GCD(1, 213) = ( 1 x 213 ) / 213

= 1 / 213

= 1

So, Greatest Common Divisor of 858, 391, 901, 213 is 1
