HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 862, 698, 518 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 862, 698, 518 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 862, 698, 518 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 862, 698, 518 is 2.
HCF(862, 698, 518) = 2
HCF of 862, 698, 518 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 862, 698, 518 is 2.
Highest Common Factor of 862,698,518 is 2
Step 1: Since 862 > 698, we apply the division lemma to 862 and 698, to get
862 = 698 x 1 + 164
Step 2: Since the reminder 698 ≠ 0, we apply division lemma to 164 and 698, to get
698 = 164 x 4 + 42
Step 3: We consider the new divisor 164 and the new remainder 42, and apply the division lemma to get
164 = 42 x 3 + 38
We consider the new divisor 42 and the new remainder 38,and apply the division lemma to get
42 = 38 x 1 + 4
We consider the new divisor 38 and the new remainder 4,and apply the division lemma to get
38 = 4 x 9 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 862 and 698 is 2
Notice that 2 = HCF(4,2) = HCF(38,4) = HCF(42,38) = HCF(164,42) = HCF(698,164) = HCF(862,698) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 518 > 2, we apply the division lemma to 518 and 2, to get
518 = 2 x 259 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 518 is 2
Notice that 2 = HCF(518,2) .
