Given numbers are 978, 132, 399, 830

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

Apply this formula for all numbers.

Step1:

LCM(978, 132) = 21516

GCD(978, 132) = ( 978 x 132 ) / 21516

= 978 / 132

= 978

Step2:

LCM(6, 399) = 798

GCD(6, 399) = ( 6 x 399 ) / 798

= 6 / 399

= 6

Step3:

LCM(3, 830) = 2490

GCD(3, 830) = ( 3 x 830 ) / 2490

= 3 / 830

= 3

So, Greatest Common Divisor of 978, 132, 399, 830 is 1
