Given numbers are 398, 746, 174, 663
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(398, 746) = 148454
GCD(398, 746) = ( 398 x 746 ) / 148454
= 398 / 746
= 398
Step2:
LCM(2, 174) = 174
GCD(2, 174) = ( 2 x 174 ) / 174
= 2 / 174
= 2
Step3:
LCM(2, 663) = 1326
GCD(2, 663) = ( 2 x 663 ) / 1326
= 2 / 663
= 2
So, Greatest Common Divisor of 398, 746, 174, 663 is 1
