HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 518, 74047 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 518, 74047 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 518, 74047 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, 74047 is 1.
HCF(518, 74047) = 1
HCF of 518, 74047 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, 74047 is 1.
Highest Common Factor of 518,74047 is 1
Step 1: Since 74047 > 518, we apply the division lemma to 74047 and 518, to get
74047 = 518 x 142 + 491
Step 2: Since the reminder 518 ≠ 0, we apply division lemma to 491 and 518, to get
518 = 491 x 1 + 27
Step 3: We consider the new divisor 491 and the new remainder 27, and apply the division lemma to get
491 = 27 x 18 + 5
We consider the new divisor 27 and the new remainder 5,and apply the division lemma to get
27 = 5 x 5 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 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 518 and 74047 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(27,5) = HCF(491,27) = HCF(518,491) = HCF(74047,518) .
