HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 491, 895, 18, 264 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 491, 895, 18, 264 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 491, 895, 18, 264 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 491, 895, 18, 264 is 1.
HCF(491, 895, 18, 264) = 1
HCF of 491, 895, 18, 264 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 491, 895, 18, 264 is 1.
Highest Common Factor of 491,895,18,264 is 1
Step 1: Since 895 > 491, we apply the division lemma to 895 and 491, to get
895 = 491 x 1 + 404
Step 2: Since the reminder 491 ≠ 0, we apply division lemma to 404 and 491, to get
491 = 404 x 1 + 87
Step 3: We consider the new divisor 404 and the new remainder 87, and apply the division lemma to get
404 = 87 x 4 + 56
We consider the new divisor 87 and the new remainder 56,and apply the division lemma to get
87 = 56 x 1 + 31
We consider the new divisor 56 and the new remainder 31,and apply the division lemma to get
56 = 31 x 1 + 25
We consider the new divisor 31 and the new remainder 25,and apply the division lemma to get
31 = 25 x 1 + 6
We consider the new divisor 25 and the new remainder 6,and apply the division lemma to get
25 = 6 x 4 + 1
We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 491 and 895 is 1
Notice that 1 = HCF(6,1) = HCF(25,6) = HCF(31,25) = HCF(56,31) = HCF(87,56) = HCF(404,87) = HCF(491,404) = HCF(895,491) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 18 > 1, we apply the division lemma to 18 and 1, to get
18 = 1 x 18 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 18 is 1
Notice that 1 = HCF(18,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 264 > 1, we apply the division lemma to 264 and 1, to get
264 = 1 x 264 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 264 is 1
Notice that 1 = HCF(264,1) .
