HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 833, 491, 315 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 833, 491, 315 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 833, 491, 315 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 833, 491, 315 is 1.
HCF(833, 491, 315) = 1
HCF of 833, 491, 315 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 833, 491, 315 is 1.
Highest Common Factor of 833,491,315 is 1
Step 1: Since 833 > 491, we apply the division lemma to 833 and 491, to get
833 = 491 x 1 + 342
Step 2: Since the reminder 491 ≠ 0, we apply division lemma to 342 and 491, to get
491 = 342 x 1 + 149
Step 3: We consider the new divisor 342 and the new remainder 149, and apply the division lemma to get
342 = 149 x 2 + 44
We consider the new divisor 149 and the new remainder 44,and apply the division lemma to get
149 = 44 x 3 + 17
We consider the new divisor 44 and the new remainder 17,and apply the division lemma to get
44 = 17 x 2 + 10
We consider the new divisor 17 and the new remainder 10,and apply the division lemma to get
17 = 10 x 1 + 7
We consider the new divisor 10 and the new remainder 7,and apply the division lemma to get
10 = 7 x 1 + 3
We consider the new divisor 7 and the new remainder 3,and apply the division lemma to get
7 = 3 x 2 + 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 833 and 491 is 1
Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(10,7) = HCF(17,10) = HCF(44,17) = HCF(149,44) = HCF(342,149) = HCF(491,342) = HCF(833,491) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 315 > 1, we apply the division lemma to 315 and 1, to get
315 = 1 x 315 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 315 is 1
Notice that 1 = HCF(315,1) .
