Given numbers are 978, 630, 13, 850

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

Apply this formula for all numbers.

Step1:

LCM(978, 630) = 102690

GCD(978, 630) = ( 978 x 630 ) / 102690

= 978 / 630

= 978

Step2:

LCM(6, 13) = 78

GCD(6, 13) = ( 6 x 13 ) / 78

= 6 / 13

= 6

Step3:

LCM(1, 850) = 850

GCD(1, 850) = ( 1 x 850 ) / 850

= 1 / 850

= 1

So, Greatest Common Divisor of 978, 630, 13, 850 is 1
