Given numbers are 838, 856, 70

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

Apply this formula for all numbers.

Step1:

LCM(838, 856) = 358664

GCD(838, 856) = ( 838 x 856 ) / 358664

= 838 / 856

= 838

Step2:

LCM(2, 70) = 70

GCD(2, 70) = ( 2 x 70 ) / 70

= 2 / 70

= 2

So, Greatest Common Divisor of 838, 856, 70 is 2
