HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 289, 807, 995, 431 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 289, 807, 995, 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 289, 807, 995, 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 289, 807, 995, 431 is 1.
HCF(289, 807, 995, 431) = 1
HCF of 289, 807, 995, 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 289, 807, 995, 431 is 1.
Highest Common Factor of 289,807,995,431 is 1
Step 1: Since 807 > 289, we apply the division lemma to 807 and 289, to get
807 = 289 x 2 + 229
Step 2: Since the reminder 289 ≠ 0, we apply division lemma to 229 and 289, to get
289 = 229 x 1 + 60
Step 3: We consider the new divisor 229 and the new remainder 60, and apply the division lemma to get
229 = 60 x 3 + 49
We consider the new divisor 60 and the new remainder 49,and apply the division lemma to get
60 = 49 x 1 + 11
We consider the new divisor 49 and the new remainder 11,and apply the division lemma to get
49 = 11 x 4 + 5
We consider the new divisor 11 and the new remainder 5,and apply the division lemma to get
11 = 5 x 2 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 289 and 807 is 1
Notice that 1 = HCF(5,1) = HCF(11,5) = HCF(49,11) = HCF(60,49) = HCF(229,60) = HCF(289,229) = HCF(807,289) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 995 > 1, we apply the division lemma to 995 and 1, to get
995 = 1 x 995 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 995 is 1
Notice that 1 = HCF(995,1) .
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) .
