HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 428, 812 i.e. 4 the largest integer that leaves a remainder zero for all numbers.
HCF of 428, 812 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 428, 812 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 428, 812 is 4.
HCF(428, 812) = 4
HCF of 428, 812 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 428, 812 is 4.
Highest Common Factor of 428,812 is 4
Step 1: Since 812 > 428, we apply the division lemma to 812 and 428, to get
812 = 428 x 1 + 384
Step 2: Since the reminder 428 ≠ 0, we apply division lemma to 384 and 428, to get
428 = 384 x 1 + 44
Step 3: We consider the new divisor 384 and the new remainder 44, and apply the division lemma to get
384 = 44 x 8 + 32
We consider the new divisor 44 and the new remainder 32,and apply the division lemma to get
44 = 32 x 1 + 12
We consider the new divisor 32 and the new remainder 12,and apply the division lemma to get
32 = 12 x 2 + 8
We consider the new divisor 12 and the new remainder 8,and apply the division lemma to get
12 = 8 x 1 + 4
We consider the new divisor 8 and the new remainder 4,and apply the division lemma to get
8 = 4 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 428 and 812 is 4
Notice that 4 = HCF(8,4) = HCF(12,8) = HCF(32,12) = HCF(44,32) = HCF(384,44) = HCF(428,384) = HCF(812,428) .
