HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 812, 468 i.e. 4 the largest integer that leaves a remainder zero for all numbers.
HCF of 812, 468 is 4 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 812, 468 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 812, 468 is 4.
HCF(812, 468) = 4
HCF of 812, 468 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 812, 468 is 4.
Highest Common Factor of 812,468 is 4
Step 1: Since 812 > 468, we apply the division lemma to 812 and 468, to get
812 = 468 x 1 + 344
Step 2: Since the reminder 468 ≠ 0, we apply division lemma to 344 and 468, to get
468 = 344 x 1 + 124
Step 3: We consider the new divisor 344 and the new remainder 124, and apply the division lemma to get
344 = 124 x 2 + 96
We consider the new divisor 124 and the new remainder 96,and apply the division lemma to get
124 = 96 x 1 + 28
We consider the new divisor 96 and the new remainder 28,and apply the division lemma to get
96 = 28 x 3 + 12
We consider the new divisor 28 and the new remainder 12,and apply the division lemma to get
28 = 12 x 2 + 4
We consider the new divisor 12 and the new remainder 4,and apply the division lemma to get
12 = 4 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 812 and 468 is 4
Notice that 4 = HCF(12,4) = HCF(28,12) = HCF(96,28) = HCF(124,96) = HCF(344,124) = HCF(468,344) = HCF(812,468) .
