Given numbers are 666, 405, 124, 978

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

Apply this formula for all numbers.

Step1:

LCM(666, 405) = 29970

GCD(666, 405) = ( 666 x 405 ) / 29970

= 666 / 405

= 666

Step2:

LCM(9, 124) = 1116

GCD(9, 124) = ( 9 x 124 ) / 1116

= 9 / 124

= 9

Step3:

LCM(1, 978) = 978

GCD(1, 978) = ( 1 x 978 ) / 978

= 1 / 978

= 1

So, Greatest Common Divisor of 666, 405, 124, 978 is 1
