HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 864, 456 i.e. 24 the largest integer that leaves a remainder zero for all numbers.
HCF of 864, 456 is 24 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 864, 456 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 864, 456 is 24.
HCF(864, 456) = 24
HCF of 864, 456 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 864, 456 is 24.
Highest Common Factor of 864,456 is 24
Step 1: Since 864 > 456, we apply the division lemma to 864 and 456, to get
864 = 456 x 1 + 408
Step 2: Since the reminder 456 ≠ 0, we apply division lemma to 408 and 456, to get
456 = 408 x 1 + 48
Step 3: We consider the new divisor 408 and the new remainder 48, and apply the division lemma to get
408 = 48 x 8 + 24
We consider the new divisor 48 and the new remainder 24, and apply the division lemma to get
48 = 24 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 24, the HCF of 864 and 456 is 24
Notice that 24 = HCF(48,24) = HCF(408,48) = HCF(456,408) = HCF(864,456) .
