Given numbers are 840, 395, 265, 780

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

Apply this formula for all numbers.

Step1:

LCM(840, 395) = 66360

GCD(840, 395) = ( 840 x 395 ) / 66360

= 840 / 395

= 840

Step2:

LCM(5, 265) = 265

GCD(5, 265) = ( 5 x 265 ) / 265

= 5 / 265

= 5

Step3:

LCM(5, 780) = 780

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

= 5 / 780

= 5

So, Greatest Common Divisor of 840, 395, 265, 780 is 5
