Given numbers are 715, 570, 790, 655

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

Apply this formula for all numbers.

Step1:

LCM(715, 570) = 81510

GCD(715, 570) = ( 715 x 570 ) / 81510

= 715 / 570

= 715

Step2:

LCM(5, 790) = 790

GCD(5, 790) = ( 5 x 790 ) / 790

= 5 / 790

= 5

Step3:

LCM(5, 655) = 655

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

= 5 / 655

= 5

So, Greatest Common Divisor of 715, 570, 790, 655 is 5
