Given numbers are 621, 149, 126

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

Apply this formula for all numbers.

Step1:

LCM(621, 149) = 92529

GCD(621, 149) = ( 621 x 149 ) / 92529

= 621 / 149

= 621

Step2:

LCM(1, 126) = 126

GCD(1, 126) = ( 1 x 126 ) / 126

= 1 / 126

= 1

So, Greatest Common Divisor of 621, 149, 126 is 1
