HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 989, 665 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 989, 665 is 1 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.
Consider we have numbers 989, 665 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b
Highest common factor (HCF) of 989, 665 is 1.
HCF(989, 665) = 1
HCF of 989, 665 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 989, 665 is 1.
Highest Common Factor of 989,665 is 1
Step 1: Since 989 > 665, we apply the division lemma to 989 and 665, to get
989 = 665 x 1 + 324
Step 2: Since the reminder 665 ≠ 0, we apply division lemma to 324 and 665, to get
665 = 324 x 2 + 17
Step 3: We consider the new divisor 324 and the new remainder 17, and apply the division lemma to get
324 = 17 x 19 + 1
We consider the new divisor 17 and the new remainder 1, and apply the division lemma to get
17 = 1 x 17 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 989 and 665 is 1
Notice that 1 = HCF(17,1) = HCF(324,17) = HCF(665,324) = HCF(989,665) .
