HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 300, 768, 812 i.e. 4 the largest integer that leaves a remainder zero for all numbers.
HCF of 300, 768, 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 300, 768, 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 300, 768, 812 is 4.
HCF(300, 768, 812) = 4
HCF of 300, 768, 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 300, 768, 812 is 4.
Highest Common Factor of 300,768,812 is 4
Step 1: Since 768 > 300, we apply the division lemma to 768 and 300, to get
768 = 300 x 2 + 168
Step 2: Since the reminder 300 ≠ 0, we apply division lemma to 168 and 300, to get
300 = 168 x 1 + 132
Step 3: We consider the new divisor 168 and the new remainder 132, and apply the division lemma to get
168 = 132 x 1 + 36
We consider the new divisor 132 and the new remainder 36,and apply the division lemma to get
132 = 36 x 3 + 24
We consider the new divisor 36 and the new remainder 24,and apply the division lemma to get
36 = 24 x 1 + 12
We consider the new divisor 24 and the new remainder 12,and apply the division lemma to get
24 = 12 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 12, the HCF of 300 and 768 is 12
Notice that 12 = HCF(24,12) = HCF(36,24) = HCF(132,36) = HCF(168,132) = HCF(300,168) = HCF(768,300) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 812 > 12, we apply the division lemma to 812 and 12, to get
812 = 12 x 67 + 8
Step 2: Since the reminder 12 ≠ 0, we apply division lemma to 8 and 12, to get
12 = 8 x 1 + 4
Step 3: 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 12 and 812 is 4
Notice that 4 = HCF(8,4) = HCF(12,8) = HCF(812,12) .
