HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 466, 639 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 466, 639 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 466, 639 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 466, 639 is 1.
HCF(466, 639) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 466, 639 is 1.
Step 1: Since 639 > 466, we apply the division lemma to 639 and 466, to get
639 = 466 x 1 + 173
Step 2: Since the reminder 466 ≠ 0, we apply division lemma to 173 and 466, to get
466 = 173 x 2 + 120
Step 3: We consider the new divisor 173 and the new remainder 120, and apply the division lemma to get
173 = 120 x 1 + 53
We consider the new divisor 120 and the new remainder 53,and apply the division lemma to get
120 = 53 x 2 + 14
We consider the new divisor 53 and the new remainder 14,and apply the division lemma to get
53 = 14 x 3 + 11
We consider the new divisor 14 and the new remainder 11,and apply the division lemma to get
14 = 11 x 1 + 3
We consider the new divisor 11 and the new remainder 3,and apply the division lemma to get
11 = 3 x 3 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 466 and 639 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(11,3) = HCF(14,11) = HCF(53,14) = HCF(120,53) = HCF(173,120) = HCF(466,173) = HCF(639,466) .
Here are some samples of HCF using Euclid's Algorithm calculations.
