HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 671, 526, 521 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 671, 526, 521 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, 526, 521 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, 526, 521 is 1.
HCF(671, 526, 521) = 1
HCF of 671, 526, 521 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, 526, 521 is 1.
Highest Common Factor of 671,526,521 is 1
Step 1: Since 671 > 526, we apply the division lemma to 671 and 526, to get
671 = 526 x 1 + 145
Step 2: Since the reminder 526 ≠ 0, we apply division lemma to 145 and 526, to get
526 = 145 x 3 + 91
Step 3: We consider the new divisor 145 and the new remainder 91, and apply the division lemma to get
145 = 91 x 1 + 54
We consider the new divisor 91 and the new remainder 54,and apply the division lemma to get
91 = 54 x 1 + 37
We consider the new divisor 54 and the new remainder 37,and apply the division lemma to get
54 = 37 x 1 + 17
We consider the new divisor 37 and the new remainder 17,and apply the division lemma to get
37 = 17 x 2 + 3
We consider the new divisor 17 and the new remainder 3,and apply the division lemma to get
17 = 3 x 5 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 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 671 and 526 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(17,3) = HCF(37,17) = HCF(54,37) = HCF(91,54) = HCF(145,91) = HCF(526,145) = HCF(671,526) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 521 > 1, we apply the division lemma to 521 and 1, to get
521 = 1 x 521 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 521 is 1
Notice that 1 = HCF(521,1) .
