Given numbers are 351, 689, 136, 745

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

Apply this formula for all numbers.

Step1:

LCM(351, 689) = 18603

GCD(351, 689) = ( 351 x 689 ) / 18603

= 351 / 689

= 351

Step2:

LCM(13, 136) = 1768

GCD(13, 136) = ( 13 x 136 ) / 1768

= 13 / 136

= 13

Step3:

LCM(1, 745) = 745

GCD(1, 745) = ( 1 x 745 ) / 745

= 1 / 745

= 1

So, Greatest Common Divisor of 351, 689, 136, 745 is 1
