HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 498, 889, 17, 891 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 498, 889, 17, 891 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 498, 889, 17, 891 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 498, 889, 17, 891 is 1.
HCF(498, 889, 17, 891) = 1
HCF of 498, 889, 17, 891 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 498, 889, 17, 891 is 1.
Highest Common Factor of 498,889,17,891 is 1
Step 1: Since 889 > 498, we apply the division lemma to 889 and 498, to get
889 = 498 x 1 + 391
Step 2: Since the reminder 498 ≠ 0, we apply division lemma to 391 and 498, to get
498 = 391 x 1 + 107
Step 3: We consider the new divisor 391 and the new remainder 107, and apply the division lemma to get
391 = 107 x 3 + 70
We consider the new divisor 107 and the new remainder 70,and apply the division lemma to get
107 = 70 x 1 + 37
We consider the new divisor 70 and the new remainder 37,and apply the division lemma to get
70 = 37 x 1 + 33
We consider the new divisor 37 and the new remainder 33,and apply the division lemma to get
37 = 33 x 1 + 4
We consider the new divisor 33 and the new remainder 4,and apply the division lemma to get
33 = 4 x 8 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 498 and 889 is 1
Notice that 1 = HCF(4,1) = HCF(33,4) = HCF(37,33) = HCF(70,37) = HCF(107,70) = HCF(391,107) = HCF(498,391) = HCF(889,498) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 17 > 1, we apply the division lemma to 17 and 1, to get
17 = 1 x 17 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 17 is 1
Notice that 1 = HCF(17,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 891 > 1, we apply the division lemma to 891 and 1, to get
891 = 1 x 891 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 891 is 1
Notice that 1 = HCF(891,1) .
