HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 630, 673 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 630, 673 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 630, 673 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 630, 673 is 1.
HCF(630, 673) = 1
HCF of 630, 673 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 630, 673 is 1.
Highest Common Factor of 630,673 is 1
Step 1: Since 673 > 630, we apply the division lemma to 673 and 630, to get
673 = 630 x 1 + 43
Step 2: Since the reminder 630 ≠ 0, we apply division lemma to 43 and 630, to get
630 = 43 x 14 + 28
Step 3: We consider the new divisor 43 and the new remainder 28, and apply the division lemma to get
43 = 28 x 1 + 15
We consider the new divisor 28 and the new remainder 15,and apply the division lemma to get
28 = 15 x 1 + 13
We consider the new divisor 15 and the new remainder 13,and apply the division lemma to get
15 = 13 x 1 + 2
We consider the new divisor 13 and the new remainder 2,and apply the division lemma to get
13 = 2 x 6 + 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 630 and 673 is 1
Notice that 1 = HCF(2,1) = HCF(13,2) = HCF(15,13) = HCF(28,15) = HCF(43,28) = HCF(630,43) = HCF(673,630) .
