HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 517, 939 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 517, 939 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 517, 939 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 517, 939 is 1.
HCF(517, 939) = 1
HCF of 517, 939 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 517, 939 is 1.
Highest Common Factor of 517,939 is 1
Step 1: Since 939 > 517, we apply the division lemma to 939 and 517, to get
939 = 517 x 1 + 422
Step 2: Since the reminder 517 ≠ 0, we apply division lemma to 422 and 517, to get
517 = 422 x 1 + 95
Step 3: We consider the new divisor 422 and the new remainder 95, and apply the division lemma to get
422 = 95 x 4 + 42
We consider the new divisor 95 and the new remainder 42,and apply the division lemma to get
95 = 42 x 2 + 11
We consider the new divisor 42 and the new remainder 11,and apply the division lemma to get
42 = 11 x 3 + 9
We consider the new divisor 11 and the new remainder 9,and apply the division lemma to get
11 = 9 x 1 + 2
We consider the new divisor 9 and the new remainder 2,and apply the division lemma to get
9 = 2 x 4 + 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 517 and 939 is 1
Notice that 1 = HCF(2,1) = HCF(9,2) = HCF(11,9) = HCF(42,11) = HCF(95,42) = HCF(422,95) = HCF(517,422) = HCF(939,517) .
