Given numbers are 720, 715, 190, 155

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

Apply this formula for all numbers.

Step1:

LCM(720, 715) = 102960

GCD(720, 715) = ( 720 x 715 ) / 102960

= 720 / 715

= 720

Step2:

LCM(5, 190) = 190

GCD(5, 190) = ( 5 x 190 ) / 190

= 5 / 190

= 5

Step3:

LCM(5, 155) = 155

GCD(5, 155) = ( 5 x 155 ) / 155

= 5 / 155

= 5

So, Greatest Common Divisor of 720, 715, 190, 155 is 5
