HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 518, 846 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 518, 846 is 2 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 518, 846 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 518, 846 is 2.
HCF(518, 846) = 2
HCF of 518, 846 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 518, 846 is 2.
Highest Common Factor of 518,846 is 2
Step 1: Since 846 > 518, we apply the division lemma to 846 and 518, to get
846 = 518 x 1 + 328
Step 2: Since the reminder 518 ≠ 0, we apply division lemma to 328 and 518, to get
518 = 328 x 1 + 190
Step 3: We consider the new divisor 328 and the new remainder 190, and apply the division lemma to get
328 = 190 x 1 + 138
We consider the new divisor 190 and the new remainder 138,and apply the division lemma to get
190 = 138 x 1 + 52
We consider the new divisor 138 and the new remainder 52,and apply the division lemma to get
138 = 52 x 2 + 34
We consider the new divisor 52 and the new remainder 34,and apply the division lemma to get
52 = 34 x 1 + 18
We consider the new divisor 34 and the new remainder 18,and apply the division lemma to get
34 = 18 x 1 + 16
We consider the new divisor 18 and the new remainder 16,and apply the division lemma to get
18 = 16 x 1 + 2
We consider the new divisor 16 and the new remainder 2,and apply the division lemma to get
16 = 2 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 518 and 846 is 2
Notice that 2 = HCF(16,2) = HCF(18,16) = HCF(34,18) = HCF(52,34) = HCF(138,52) = HCF(190,138) = HCF(328,190) = HCF(518,328) = HCF(846,518) .
