Given numbers are 440, 780, 258, 780

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

Apply this formula for all numbers.

Step1:

LCM(440, 780) = 17160

GCD(440, 780) = ( 440 x 780 ) / 17160

= 440 / 780

= 440

Step2:

LCM(20, 258) = 2580

GCD(20, 258) = ( 20 x 258 ) / 2580

= 20 / 258

= 20

Step3:

LCM(2, 780) = 780

GCD(2, 780) = ( 2 x 780 ) / 780

= 2 / 780

= 2

So, Greatest Common Divisor of 440, 780, 258, 780 is 2
