HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 805, 946 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 805, 946 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 805, 946 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 805, 946 is 1.
HCF(805, 946) = 1
HCF of 805, 946 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 805, 946 is 1.
Highest Common Factor of 805,946 is 1
Step 1: Since 946 > 805, we apply the division lemma to 946 and 805, to get
946 = 805 x 1 + 141
Step 2: Since the reminder 805 ≠ 0, we apply division lemma to 141 and 805, to get
805 = 141 x 5 + 100
Step 3: We consider the new divisor 141 and the new remainder 100, and apply the division lemma to get
141 = 100 x 1 + 41
We consider the new divisor 100 and the new remainder 41,and apply the division lemma to get
100 = 41 x 2 + 18
We consider the new divisor 41 and the new remainder 18,and apply the division lemma to get
41 = 18 x 2 + 5
We consider the new divisor 18 and the new remainder 5,and apply the division lemma to get
18 = 5 x 3 + 3
We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get
5 = 3 x 1 + 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 805 and 946 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(18,5) = HCF(41,18) = HCF(100,41) = HCF(141,100) = HCF(805,141) = HCF(946,805) .
