HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 436, 814, 731, 20 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 436, 814, 731, 20 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 436, 814, 731, 20 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 436, 814, 731, 20 is 1.
HCF(436, 814, 731, 20) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 436, 814, 731, 20 is 1.
Step 1: Since 814 > 436, we apply the division lemma to 814 and 436, to get
814 = 436 x 1 + 378
Step 2: Since the reminder 436 ≠ 0, we apply division lemma to 378 and 436, to get
436 = 378 x 1 + 58
Step 3: We consider the new divisor 378 and the new remainder 58, and apply the division lemma to get
378 = 58 x 6 + 30
We consider the new divisor 58 and the new remainder 30,and apply the division lemma to get
58 = 30 x 1 + 28
We consider the new divisor 30 and the new remainder 28,and apply the division lemma to get
30 = 28 x 1 + 2
We consider the new divisor 28 and the new remainder 2,and apply the division lemma to get
28 = 2 x 14 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 436 and 814 is 2
Notice that 2 = HCF(28,2) = HCF(30,28) = HCF(58,30) = HCF(378,58) = HCF(436,378) = HCF(814,436) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 731 > 2, we apply the division lemma to 731 and 2, to get
731 = 2 x 365 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 731 is 1
Notice that 1 = HCF(2,1) = HCF(731,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 20 > 1, we apply the division lemma to 20 and 1, to get
20 = 1 x 20 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 20 is 1
Notice that 1 = HCF(20,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
