Given numbers are 289, 720, 98, 693

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

Apply this formula for all numbers.

Step1:

LCM(289, 720) = 208080

GCD(289, 720) = ( 289 x 720 ) / 208080

= 289 / 720

= 289

Step2:

LCM(1, 98) = 98

GCD(1, 98) = ( 1 x 98 ) / 98

= 1 / 98

= 1

Step3:

LCM(1, 693) = 693

GCD(1, 693) = ( 1 x 693 ) / 693

= 1 / 693

= 1

So, Greatest Common Divisor of 289, 720, 98, 693 is 1
