HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 670, 723 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 670, 723 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 670, 723 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 670, 723 is 1.
HCF(670, 723) = 1
HCF of 670, 723 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 670, 723 is 1.
Highest Common Factor of 670,723 is 1
Step 1: Since 723 > 670, we apply the division lemma to 723 and 670, to get
723 = 670 x 1 + 53
Step 2: Since the reminder 670 ≠ 0, we apply division lemma to 53 and 670, to get
670 = 53 x 12 + 34
Step 3: We consider the new divisor 53 and the new remainder 34, and apply the division lemma to get
53 = 34 x 1 + 19
We consider the new divisor 34 and the new remainder 19,and apply the division lemma to get
34 = 19 x 1 + 15
We consider the new divisor 19 and the new remainder 15,and apply the division lemma to get
19 = 15 x 1 + 4
We consider the new divisor 15 and the new remainder 4,and apply the division lemma to get
15 = 4 x 3 + 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 670 and 723 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(15,4) = HCF(19,15) = HCF(34,19) = HCF(53,34) = HCF(670,53) = HCF(723,670) .
