Given numbers are 770, 640, 402, 752

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

Apply this formula for all numbers.

Step1:

LCM(770, 640) = 49280

GCD(770, 640) = ( 770 x 640 ) / 49280

= 770 / 640

= 770

Step2:

LCM(10, 402) = 2010

GCD(10, 402) = ( 10 x 402 ) / 2010

= 10 / 402

= 10

Step3:

LCM(2, 752) = 752

GCD(2, 752) = ( 2 x 752 ) / 752

= 2 / 752

= 2

So, Greatest Common Divisor of 770, 640, 402, 752 is 2
