HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 801, 4686 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 801, 4686 is 3 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 801, 4686 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 801, 4686 is 3.
HCF(801, 4686) = 3
HCF of 801, 4686 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 801, 4686 is 3.
Highest Common Factor of 801,4686 is 3
Step 1: Since 4686 > 801, we apply the division lemma to 4686 and 801, to get
4686 = 801 x 5 + 681
Step 2: Since the reminder 801 ≠ 0, we apply division lemma to 681 and 801, to get
801 = 681 x 1 + 120
Step 3: We consider the new divisor 681 and the new remainder 120, and apply the division lemma to get
681 = 120 x 5 + 81
We consider the new divisor 120 and the new remainder 81,and apply the division lemma to get
120 = 81 x 1 + 39
We consider the new divisor 81 and the new remainder 39,and apply the division lemma to get
81 = 39 x 2 + 3
We consider the new divisor 39 and the new remainder 3,and apply the division lemma to get
39 = 3 x 13 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 801 and 4686 is 3
Notice that 3 = HCF(39,3) = HCF(81,39) = HCF(120,81) = HCF(681,120) = HCF(801,681) = HCF(4686,801) .
