Given numbers are 154, 476, 138, 947

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

Apply this formula for all numbers.

Step1:

LCM(154, 476) = 5236

GCD(154, 476) = ( 154 x 476 ) / 5236

= 154 / 476

= 154

Step2:

LCM(14, 138) = 966

GCD(14, 138) = ( 14 x 138 ) / 966

= 14 / 138

= 14

Step3:

LCM(2, 947) = 1894

GCD(2, 947) = ( 2 x 947 ) / 1894

= 2 / 947

= 2

So, Greatest Common Divisor of 154, 476, 138, 947 is 1
