HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 44, 73, 21, 431 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 44, 73, 21, 431 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 44, 73, 21, 431 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 44, 73, 21, 431 is 1.
HCF(44, 73, 21, 431) = 1
HCF of 44, 73, 21, 431 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 44, 73, 21, 431 is 1.
Highest Common Factor of 44,73,21,431 is 1
Step 1: Since 73 > 44, we apply the division lemma to 73 and 44, to get
73 = 44 x 1 + 29
Step 2: Since the reminder 44 ≠ 0, we apply division lemma to 29 and 44, to get
44 = 29 x 1 + 15
Step 3: We consider the new divisor 29 and the new remainder 15, and apply the division lemma to get
29 = 15 x 1 + 14
We consider the new divisor 15 and the new remainder 14,and apply the division lemma to get
15 = 14 x 1 + 1
We consider the new divisor 14 and the new remainder 1,and apply the division lemma 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 44 and 73 is 1
Notice that 1 = HCF(14,1) = HCF(15,14) = HCF(29,15) = HCF(44,29) = HCF(73,44) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 21 > 1, we apply the division lemma to 21 and 1, to get
21 = 1 x 21 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 21 is 1
Notice that 1 = HCF(21,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 431 > 1, we apply the division lemma to 431 and 1, to get
431 = 1 x 431 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 431 is 1
Notice that 1 = HCF(431,1) .
