Given numbers are 640, 970, 409, 935

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

Apply this formula for all numbers.

Step1:

LCM(640, 970) = 62080

GCD(640, 970) = ( 640 x 970 ) / 62080

= 640 / 970

= 640

Step2:

LCM(10, 409) = 4090

GCD(10, 409) = ( 10 x 409 ) / 4090

= 10 / 409

= 10

Step3:

LCM(1, 935) = 935

GCD(1, 935) = ( 1 x 935 ) / 935

= 1 / 935

= 1

So, Greatest Common Divisor of 640, 970, 409, 935 is 1
