Given numbers are 890, 694, 15, 398
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(890, 694) = 308830
GCD(890, 694) = ( 890 x 694 ) / 308830
= 890 / 694
= 890
Step2:
LCM(2, 15) = 30
GCD(2, 15) = ( 2 x 15 ) / 30
= 2 / 15
= 2
Step3:
LCM(1, 398) = 398
GCD(1, 398) = ( 1 x 398 ) / 398
= 1 / 398
= 1
So, Greatest Common Divisor of 890, 694, 15, 398 is 1
