HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 393, 929, 391 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 393, 929, 391 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 393, 929, 391 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 393, 929, 391 is 1.
HCF(393, 929, 391) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 393, 929, 391 is 1.
Step 1: Since 929 > 393, we apply the division lemma to 929 and 393, to get
929 = 393 x 2 + 143
Step 2: Since the reminder 393 ≠ 0, we apply division lemma to 143 and 393, to get
393 = 143 x 2 + 107
Step 3: We consider the new divisor 143 and the new remainder 107, and apply the division lemma to get
143 = 107 x 1 + 36
We consider the new divisor 107 and the new remainder 36,and apply the division lemma to get
107 = 36 x 2 + 35
We consider the new divisor 36 and the new remainder 35,and apply the division lemma to get
36 = 35 x 1 + 1
We consider the new divisor 35 and the new remainder 1,and apply the division lemma to get
35 = 1 x 35 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 393 and 929 is 1
Notice that 1 = HCF(35,1) = HCF(36,35) = HCF(107,36) = HCF(143,107) = HCF(393,143) = HCF(929,393) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 391 > 1, we apply the division lemma to 391 and 1, to get
391 = 1 x 391 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 391 is 1
Notice that 1 = HCF(391,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
