Given numbers are 445, 240, 145, 790

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

Apply this formula for all numbers.

Step1:

LCM(445, 240) = 21360

GCD(445, 240) = ( 445 x 240 ) / 21360

= 445 / 240

= 445

Step2:

LCM(5, 145) = 145

GCD(5, 145) = ( 5 x 145 ) / 145

= 5 / 145

= 5

Step3:

LCM(5, 790) = 790

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

= 5 / 790

= 5

So, Greatest Common Divisor of 445, 240, 145, 790 is 5
