Given numbers are 475, 905, 646, 148
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(475, 905) = 85975
GCD(475, 905) = ( 475 x 905 ) / 85975
= 475 / 905
= 475
Step2:
LCM(5, 646) = 3230
GCD(5, 646) = ( 5 x 646 ) / 3230
= 5 / 646
= 5
Step3:
LCM(1, 148) = 148
GCD(1, 148) = ( 1 x 148 ) / 148
= 1 / 148
= 1
So, Greatest Common Divisor of 475, 905, 646, 148 is 1
