Given numbers are 546, 176, 78, 649

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

Apply this formula for all numbers.

Step1:

LCM(546, 176) = 48048

GCD(546, 176) = ( 546 x 176 ) / 48048

= 546 / 176

= 546

Step2:

LCM(2, 78) = 78

GCD(2, 78) = ( 2 x 78 ) / 78

= 2 / 78

= 2

Step3:

LCM(2, 649) = 1298

GCD(2, 649) = ( 2 x 649 ) / 1298

= 2 / 649

= 2

So, Greatest Common Divisor of 546, 176, 78, 649 is 1
