HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 308, 784, 911, 35 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 308, 784, 911, 35 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 308, 784, 911, 35 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 308, 784, 911, 35 is 1.
HCF(308, 784, 911, 35) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 308, 784, 911, 35 is 1.
Step 1: Since 784 > 308, we apply the division lemma to 784 and 308, to get
784 = 308 x 2 + 168
Step 2: Since the reminder 308 ≠ 0, we apply division lemma to 168 and 308, to get
308 = 168 x 1 + 140
Step 3: We consider the new divisor 168 and the new remainder 140, and apply the division lemma to get
168 = 140 x 1 + 28
We consider the new divisor 140 and the new remainder 28, and apply the division lemma to get
140 = 28 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 28, the HCF of 308 and 784 is 28
Notice that 28 = HCF(140,28) = HCF(168,140) = HCF(308,168) = HCF(784,308) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 911 > 28, we apply the division lemma to 911 and 28, to get
911 = 28 x 32 + 15
Step 2: Since the reminder 28 ≠ 0, we apply division lemma to 15 and 28, to get
28 = 15 x 1 + 13
Step 3: We consider the new divisor 15 and the new remainder 13, and apply the division lemma to get
15 = 13 x 1 + 2
We consider the new divisor 13 and the new remainder 2,and apply the division lemma to get
13 = 2 x 6 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 28 and 911 is 1
Notice that 1 = HCF(2,1) = HCF(13,2) = HCF(15,13) = HCF(28,15) = HCF(911,28) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 35 > 1, we apply the division lemma to 35 and 1, to get
35 = 1 x 35 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 35 is 1
Notice that 1 = HCF(35,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
