HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 207, 518 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 207, 518 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 207, 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 207, 518 is 1.
HCF(207, 518) = 1
HCF of 207, 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 207, 518 is 1.
Highest Common Factor of 207,518 is 1
Step 1: Since 518 > 207, we apply the division lemma to 518 and 207, to get
518 = 207 x 2 + 104
Step 2: Since the reminder 207 ≠ 0, we apply division lemma to 104 and 207, to get
207 = 104 x 1 + 103
Step 3: We consider the new divisor 104 and the new remainder 103, and apply the division lemma to get
104 = 103 x 1 + 1
We consider the new divisor 103 and the new remainder 1, and apply the division lemma to get
103 = 1 x 103 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 207 and 518 is 1
Notice that 1 = HCF(103,1) = HCF(104,103) = HCF(207,104) = HCF(518,207) .
