Given numbers are 841, 770, 647, 286

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

Apply this formula for all numbers.

Step1:

LCM(841, 770) = 647570

GCD(841, 770) = ( 841 x 770 ) / 647570

= 841 / 770

= 841

Step2:

LCM(1, 647) = 647

GCD(1, 647) = ( 1 x 647 ) / 647

= 1 / 647

= 1

Step3:

LCM(1, 286) = 286

GCD(1, 286) = ( 1 x 286 ) / 286

= 1 / 286

= 1

So, Greatest Common Divisor of 841, 770, 647, 286 is 1
