Given numbers are 903, 218, 145, 646
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(903, 218) = 196854
GCD(903, 218) = ( 903 x 218 ) / 196854
= 903 / 218
= 903
Step2:
LCM(1, 145) = 145
GCD(1, 145) = ( 1 x 145 ) / 145
= 1 / 145
= 1
Step3:
LCM(1, 646) = 646
GCD(1, 646) = ( 1 x 646 ) / 646
= 1 / 646
= 1
So, Greatest Common Divisor of 903, 218, 145, 646 is 1
