HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 671, 389, 456 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 671, 389, 456 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, 389, 456 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, 389, 456 is 1.
HCF(671, 389, 456) = 1
HCF of 671, 389, 456 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, 389, 456 is 1.
Highest Common Factor of 671,389,456 is 1
Step 1: Since 671 > 389, we apply the division lemma to 671 and 389, to get
671 = 389 x 1 + 282
Step 2: Since the reminder 389 ≠ 0, we apply division lemma to 282 and 389, to get
389 = 282 x 1 + 107
Step 3: We consider the new divisor 282 and the new remainder 107, and apply the division lemma to get
282 = 107 x 2 + 68
We consider the new divisor 107 and the new remainder 68,and apply the division lemma to get
107 = 68 x 1 + 39
We consider the new divisor 68 and the new remainder 39,and apply the division lemma to get
68 = 39 x 1 + 29
We consider the new divisor 39 and the new remainder 29,and apply the division lemma to get
39 = 29 x 1 + 10
We consider the new divisor 29 and the new remainder 10,and apply the division lemma to get
29 = 10 x 2 + 9
We consider the new divisor 10 and the new remainder 9,and apply the division lemma to get
10 = 9 x 1 + 1
We consider the new divisor 9 and the new remainder 1,and apply the division lemma to get
9 = 1 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 671 and 389 is 1
Notice that 1 = HCF(9,1) = HCF(10,9) = HCF(29,10) = HCF(39,29) = HCF(68,39) = HCF(107,68) = HCF(282,107) = HCF(389,282) = HCF(671,389) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 456 > 1, we apply the division lemma to 456 and 1, to get
456 = 1 x 456 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 456 is 1
Notice that 1 = HCF(456,1) .
