Given numbers are 770, 270, 486, 646

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

Apply this formula for all numbers.

Step1:

LCM(770, 270) = 20790

GCD(770, 270) = ( 770 x 270 ) / 20790

= 770 / 270

= 770

Step2:

LCM(10, 486) = 2430

GCD(10, 486) = ( 10 x 486 ) / 2430

= 10 / 486

= 10

Step3:

LCM(2, 646) = 646

GCD(2, 646) = ( 2 x 646 ) / 646

= 2 / 646

= 2

So, Greatest Common Divisor of 770, 270, 486, 646 is 2
