Given numbers are 849, 689, 963, 858

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

Apply this formula for all numbers.

Step1:

LCM(849, 689) = 584961

GCD(849, 689) = ( 849 x 689 ) / 584961

= 849 / 689

= 849

Step2:

LCM(1, 963) = 963

GCD(1, 963) = ( 1 x 963 ) / 963

= 1 / 963

= 1

Step3:

LCM(1, 858) = 858

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

= 1 / 858

= 1

So, Greatest Common Divisor of 849, 689, 963, 858 is 1
