Given numbers are 523, 149, 428, 138
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(523, 149) = 77927
GCD(523, 149) = ( 523 x 149 ) / 77927
= 523 / 149
= 523
Step2:
LCM(1, 428) = 428
GCD(1, 428) = ( 1 x 428 ) / 428
= 1 / 428
= 1
Step3:
LCM(1, 138) = 138
GCD(1, 138) = ( 1 x 138 ) / 138
= 1 / 138
= 1
So, Greatest Common Divisor of 523, 149, 428, 138 is 1
