HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 917, 669 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 917, 669 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 917, 669 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 917, 669 is 1.
HCF(917, 669) = 1
HCF of 917, 669 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 917, 669 is 1.
Highest Common Factor of 917,669 is 1
Step 1: Since 917 > 669, we apply the division lemma to 917 and 669, to get
917 = 669 x 1 + 248
Step 2: Since the reminder 669 ≠ 0, we apply division lemma to 248 and 669, to get
669 = 248 x 2 + 173
Step 3: We consider the new divisor 248 and the new remainder 173, and apply the division lemma to get
248 = 173 x 1 + 75
We consider the new divisor 173 and the new remainder 75,and apply the division lemma to get
173 = 75 x 2 + 23
We consider the new divisor 75 and the new remainder 23,and apply the division lemma to get
75 = 23 x 3 + 6
We consider the new divisor 23 and the new remainder 6,and apply the division lemma to get
23 = 6 x 3 + 5
We consider the new divisor 6 and the new remainder 5,and apply the division lemma to get
6 = 5 x 1 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 917 and 669 is 1
Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(23,6) = HCF(75,23) = HCF(173,75) = HCF(248,173) = HCF(669,248) = HCF(917,669) .
