Given numbers are 840, 790, 844, 980

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

Apply this formula for all numbers.

Step1:

LCM(840, 790) = 66360

GCD(840, 790) = ( 840 x 790 ) / 66360

= 840 / 790

= 840

Step2:

LCM(10, 844) = 4220

GCD(10, 844) = ( 10 x 844 ) / 4220

= 10 / 844

= 10

Step3:

LCM(2, 980) = 980

GCD(2, 980) = ( 2 x 980 ) / 980

= 2 / 980

= 2

So, Greatest Common Divisor of 840, 790, 844, 980 is 2
