HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 308, 686, 281, 32 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 308, 686, 281, 32 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, 686, 281, 32 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, 686, 281, 32 is 1.
HCF(308, 686, 281, 32) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 308, 686, 281, 32 is 1.
Step 1: Since 686 > 308, we apply the division lemma to 686 and 308, to get
686 = 308 x 2 + 70
Step 2: Since the reminder 308 ≠ 0, we apply division lemma to 70 and 308, to get
308 = 70 x 4 + 28
Step 3: We consider the new divisor 70 and the new remainder 28, and apply the division lemma to get
70 = 28 x 2 + 14
We consider the new divisor 28 and the new remainder 14, and apply the division lemma to get
28 = 14 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 14, the HCF of 308 and 686 is 14
Notice that 14 = HCF(28,14) = HCF(70,28) = HCF(308,70) = HCF(686,308) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 281 > 14, we apply the division lemma to 281 and 14, to get
281 = 14 x 20 + 1
Step 2: Since the reminder 14 ≠ 0, we apply division lemma to 1 and 14, to get
14 = 1 x 14 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 14 and 281 is 1
Notice that 1 = HCF(14,1) = HCF(281,14) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 32 > 1, we apply the division lemma to 32 and 1, to get
32 = 1 x 32 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 32 is 1
Notice that 1 = HCF(32,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
