Given numbers are 530, 870, 835, 945

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

Apply this formula for all numbers.

Step1:

LCM(530, 870) = 46110

GCD(530, 870) = ( 530 x 870 ) / 46110

= 530 / 870

= 530

Step2:

LCM(10, 835) = 1670

GCD(10, 835) = ( 10 x 835 ) / 1670

= 10 / 835

= 10

Step3:

LCM(5, 945) = 945

GCD(5, 945) = ( 5 x 945 ) / 945

= 5 / 945

= 5

So, Greatest Common Divisor of 530, 870, 835, 945 is 5
