HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 671, 404, 779 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 671, 404, 779 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, 404, 779 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, 404, 779 is 1.
HCF(671, 404, 779) = 1
HCF of 671, 404, 779 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, 404, 779 is 1.
Highest Common Factor of 671,404,779 is 1
Step 1: Since 671 > 404, we apply the division lemma to 671 and 404, to get
671 = 404 x 1 + 267
Step 2: Since the reminder 404 ≠ 0, we apply division lemma to 267 and 404, to get
404 = 267 x 1 + 137
Step 3: We consider the new divisor 267 and the new remainder 137, and apply the division lemma to get
267 = 137 x 1 + 130
We consider the new divisor 137 and the new remainder 130,and apply the division lemma to get
137 = 130 x 1 + 7
We consider the new divisor 130 and the new remainder 7,and apply the division lemma to get
130 = 7 x 18 + 4
We consider the new divisor 7 and the new remainder 4,and apply the division lemma to get
7 = 4 x 1 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 671 and 404 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(130,7) = HCF(137,130) = HCF(267,137) = HCF(404,267) = HCF(671,404) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 779 > 1, we apply the division lemma to 779 and 1, to get
779 = 1 x 779 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 779 is 1
Notice that 1 = HCF(779,1) .
