Given numbers are 640, 850, 930, 970

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

Apply this formula for all numbers.

Step1:

LCM(640, 850) = 54400

GCD(640, 850) = ( 640 x 850 ) / 54400

= 640 / 850

= 640

Step2:

LCM(10, 930) = 930

GCD(10, 930) = ( 10 x 930 ) / 930

= 10 / 930

= 10

Step3:

LCM(10, 970) = 970

GCD(10, 970) = ( 10 x 970 ) / 970

= 10 / 970

= 10

So, Greatest Common Divisor of 640, 850, 930, 970 is 10
