Given numbers are 289, 649, 776, 679

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

Apply this formula for all numbers.

Step1:

LCM(289, 649) = 187561

GCD(289, 649) = ( 289 x 649 ) / 187561

= 289 / 649

= 289

Step2:

LCM(1, 776) = 776

GCD(1, 776) = ( 1 x 776 ) / 776

= 1 / 776

= 1

Step3:

LCM(1, 679) = 679

GCD(1, 679) = ( 1 x 679 ) / 679

= 1 / 679

= 1

So, Greatest Common Divisor of 289, 649, 776, 679 is 1
