HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 518, 462, 490 i.e. 14 the largest integer that leaves a remainder zero for all numbers.
HCF of 518, 462, 490 is 14 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, 462, 490 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, 462, 490 is 14.
HCF(518, 462, 490) = 14
HCF of 518, 462, 490 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, 462, 490 is 14.
Highest Common Factor of 518,462,490 is 14
Step 1: Since 518 > 462, we apply the division lemma to 518 and 462, to get
518 = 462 x 1 + 56
Step 2: Since the reminder 462 ≠ 0, we apply division lemma to 56 and 462, to get
462 = 56 x 8 + 14
Step 3: We consider the new divisor 56 and the new remainder 14, and apply the division lemma to get
56 = 14 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 14, the HCF of 518 and 462 is 14
Notice that 14 = HCF(56,14) = HCF(462,56) = HCF(518,462) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 490 > 14, we apply the division lemma to 490 and 14, to get
490 = 14 x 35 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 14, the HCF of 14 and 490 is 14
Notice that 14 = HCF(490,14) .
