Given numbers are 845, 978, 740, 515

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

Apply this formula for all numbers.

Step1:

LCM(845, 978) = 826410

GCD(845, 978) = ( 845 x 978 ) / 826410

= 845 / 978

= 845

Step2:

LCM(1, 740) = 740

GCD(1, 740) = ( 1 x 740 ) / 740

= 1 / 740

= 1

Step3:

LCM(1, 515) = 515

GCD(1, 515) = ( 1 x 515 ) / 515

= 1 / 515

= 1

So, Greatest Common Divisor of 845, 978, 740, 515 is 1
