HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 671, 517, 325 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 671, 517, 325 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 671, 517, 325 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 671, 517, 325 is 1.
HCF(671, 517, 325) = 1
HCF of 671, 517, 325 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 671, 517, 325 is 1.
Highest Common Factor of 671,517,325 is 1
Step 1: Since 671 > 517, we apply the division lemma to 671 and 517, to get
671 = 517 x 1 + 154
Step 2: Since the reminder 517 ≠ 0, we apply division lemma to 154 and 517, to get
517 = 154 x 3 + 55
Step 3: We consider the new divisor 154 and the new remainder 55, and apply the division lemma to get
154 = 55 x 2 + 44
We consider the new divisor 55 and the new remainder 44,and apply the division lemma to get
55 = 44 x 1 + 11
We consider the new divisor 44 and the new remainder 11,and apply the division lemma to get
44 = 11 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 11, the HCF of 671 and 517 is 11
Notice that 11 = HCF(44,11) = HCF(55,44) = HCF(154,55) = HCF(517,154) = HCF(671,517) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 325 > 11, we apply the division lemma to 325 and 11, to get
325 = 11 x 29 + 6
Step 2: Since the reminder 11 ≠ 0, we apply division lemma to 6 and 11, to get
11 = 6 x 1 + 5
Step 3: We consider the new divisor 6 and the new remainder 5, and apply the division lemma to get
6 = 5 x 1 + 1
We consider the new divisor 5 and the new remainder 1, and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 11 and 325 is 1
Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(11,6) = HCF(325,11) .
