Given numbers are 610, 970, 66, 909

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

Apply this formula for all numbers.

Step1:

LCM(610, 970) = 59170

GCD(610, 970) = ( 610 x 970 ) / 59170

= 610 / 970

= 610

Step2:

LCM(10, 66) = 330

GCD(10, 66) = ( 10 x 66 ) / 330

= 10 / 66

= 10

Step3:

LCM(2, 909) = 1818

GCD(2, 909) = ( 2 x 909 ) / 1818

= 2 / 909

= 2

So, Greatest Common Divisor of 610, 970, 66, 909 is 1
