HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 744, 391, 473 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 744, 391, 473 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 744, 391, 473 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 744, 391, 473 is 1.
HCF(744, 391, 473) = 1
HCF of 744, 391, 473 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 744, 391, 473 is 1.
Highest Common Factor of 744,391,473 is 1
Step 1: Since 744 > 391, we apply the division lemma to 744 and 391, to get
744 = 391 x 1 + 353
Step 2: Since the reminder 391 ≠ 0, we apply division lemma to 353 and 391, to get
391 = 353 x 1 + 38
Step 3: We consider the new divisor 353 and the new remainder 38, and apply the division lemma to get
353 = 38 x 9 + 11
We consider the new divisor 38 and the new remainder 11,and apply the division lemma to get
38 = 11 x 3 + 5
We consider the new divisor 11 and the new remainder 5,and apply the division lemma to get
11 = 5 x 2 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 744 and 391 is 1
Notice that 1 = HCF(5,1) = HCF(11,5) = HCF(38,11) = HCF(353,38) = HCF(391,353) = HCF(744,391) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 473 > 1, we apply the division lemma to 473 and 1, to get
473 = 1 x 473 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 473 is 1
Notice that 1 = HCF(473,1) .
