Given numbers are 698, 981, 860, 378

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

Apply this formula for all numbers.

Step1:

LCM(698, 981) = 684738

GCD(698, 981) = ( 698 x 981 ) / 684738

= 698 / 981

= 698

Step2:

LCM(1, 860) = 860

GCD(1, 860) = ( 1 x 860 ) / 860

= 1 / 860

= 1

Step3:

LCM(1, 378) = 378

GCD(1, 378) = ( 1 x 378 ) / 378

= 1 / 378

= 1

So, Greatest Common Divisor of 698, 981, 860, 378 is 1
