Given numbers are 978, 753, 407

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

Apply this formula for all numbers.

Step1:

LCM(978, 753) = 245478

GCD(978, 753) = ( 978 x 753 ) / 245478

= 978 / 753

= 978

Step2:

LCM(3, 407) = 1221

GCD(3, 407) = ( 3 x 407 ) / 1221

= 3 / 407

= 3

So, Greatest Common Divisor of 978, 753, 407 is 1
