HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 451, 968, 864 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 451, 968, 864 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 451, 968, 864 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 451, 968, 864 is 1.
HCF(451, 968, 864) = 1
HCF of 451, 968, 864 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 451, 968, 864 is 1.
Highest Common Factor of 451,968,864 is 1
Step 1: Since 968 > 451, we apply the division lemma to 968 and 451, to get
968 = 451 x 2 + 66
Step 2: Since the reminder 451 ≠ 0, we apply division lemma to 66 and 451, to get
451 = 66 x 6 + 55
Step 3: We consider the new divisor 66 and the new remainder 55, and apply the division lemma to get
66 = 55 x 1 + 11
We consider the new divisor 55 and the new remainder 11, and apply the division lemma to get
55 = 11 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 11, the HCF of 451 and 968 is 11
Notice that 11 = HCF(55,11) = HCF(66,55) = HCF(451,66) = HCF(968,451) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 864 > 11, we apply the division lemma to 864 and 11, to get
864 = 11 x 78 + 6
Step 2: Since the reminder 11 ≠ 0, we apply division lemma to 6 and 11, to get
11 = 6 x 1 + 5
Step 3: We consider the new divisor 6 and the new remainder 5, and apply the division lemma to get
6 = 5 x 1 + 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 11 and 864 is 1
Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(11,6) = HCF(864,11) .
