Given numbers are 565, 620, 105, 780

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

Apply this formula for all numbers.

Step1:

LCM(565, 620) = 70060

GCD(565, 620) = ( 565 x 620 ) / 70060

= 565 / 620

= 565

Step2:

LCM(5, 105) = 105

GCD(5, 105) = ( 5 x 105 ) / 105

= 5 / 105

= 5

Step3:

LCM(5, 780) = 780

GCD(5, 780) = ( 5 x 780 ) / 780

= 5 / 780

= 5

So, Greatest Common Divisor of 565, 620, 105, 780 is 5
