Given numbers are 858, 814, 793, 780

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

Apply this formula for all numbers.

Step1:

LCM(858, 814) = 31746

GCD(858, 814) = ( 858 x 814 ) / 31746

= 858 / 814

= 858

Step2:

LCM(22, 793) = 17446

GCD(22, 793) = ( 22 x 793 ) / 17446

= 22 / 793

= 22

Step3:

LCM(1, 780) = 780

GCD(1, 780) = ( 1 x 780 ) / 780

= 1 / 780

= 1

So, Greatest Common Divisor of 858, 814, 793, 780 is 1
