HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 673, 906, 79 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 673, 906, 79 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 673, 906, 79 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 673, 906, 79 is 1.
HCF(673, 906, 79) = 1
HCF of 673, 906, 79 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 673, 906, 79 is 1.
Highest Common Factor of 673,906,79 is 1
Step 1: Since 906 > 673, we apply the division lemma to 906 and 673, to get
906 = 673 x 1 + 233
Step 2: Since the reminder 673 ≠ 0, we apply division lemma to 233 and 673, to get
673 = 233 x 2 + 207
Step 3: We consider the new divisor 233 and the new remainder 207, and apply the division lemma to get
233 = 207 x 1 + 26
We consider the new divisor 207 and the new remainder 26,and apply the division lemma to get
207 = 26 x 7 + 25
We consider the new divisor 26 and the new remainder 25,and apply the division lemma to get
26 = 25 x 1 + 1
We consider the new divisor 25 and the new remainder 1,and apply the division lemma to get
25 = 1 x 25 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 673 and 906 is 1
Notice that 1 = HCF(25,1) = HCF(26,25) = HCF(207,26) = HCF(233,207) = HCF(673,233) = HCF(906,673) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 79 > 1, we apply the division lemma to 79 and 1, to get
79 = 1 x 79 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 79 is 1
Notice that 1 = HCF(79,1) .
