Given numbers are 126, 402, 921, 256

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

Apply this formula for all numbers.

Step1:

LCM(126, 402) = 8442

GCD(126, 402) = ( 126 x 402 ) / 8442

= 126 / 402

= 126

Step2:

LCM(6, 921) = 1842

GCD(6, 921) = ( 6 x 921 ) / 1842

= 6 / 921

= 6

Step3:

LCM(3, 256) = 768

GCD(3, 256) = ( 3 x 256 ) / 768

= 3 / 256

= 3

So, Greatest Common Divisor of 126, 402, 921, 256 is 1
