Given numbers are 570, 115, 825, 655

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

Apply this formula for all numbers.

Step1:

LCM(570, 115) = 13110

GCD(570, 115) = ( 570 x 115 ) / 13110

= 570 / 115

= 570

Step2:

LCM(5, 825) = 825

GCD(5, 825) = ( 5 x 825 ) / 825

= 5 / 825

= 5

Step3:

LCM(5, 655) = 655

GCD(5, 655) = ( 5 x 655 ) / 655

= 5 / 655

= 5

So, Greatest Common Divisor of 570, 115, 825, 655 is 5
