Given numbers are 140, 686, 117, 698

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

Apply this formula for all numbers.

Step1:

LCM(140, 686) = 6860

GCD(140, 686) = ( 140 x 686 ) / 6860

= 140 / 686

= 140

Step2:

LCM(14, 117) = 1638

GCD(14, 117) = ( 14 x 117 ) / 1638

= 14 / 117

= 14

Step3:

LCM(1, 698) = 698

GCD(1, 698) = ( 1 x 698 ) / 698

= 1 / 698

= 1

So, Greatest Common Divisor of 140, 686, 117, 698 is 1
