HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 989, 25019 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 989, 25019 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 989, 25019 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 989, 25019 is 1.
HCF(989, 25019) = 1
HCF of 989, 25019 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 989, 25019 is 1.
Highest Common Factor of 989,25019 is 1
Step 1: Since 25019 > 989, we apply the division lemma to 25019 and 989, to get
25019 = 989 x 25 + 294
Step 2: Since the reminder 989 ≠ 0, we apply division lemma to 294 and 989, to get
989 = 294 x 3 + 107
Step 3: We consider the new divisor 294 and the new remainder 107, and apply the division lemma to get
294 = 107 x 2 + 80
We consider the new divisor 107 and the new remainder 80,and apply the division lemma to get
107 = 80 x 1 + 27
We consider the new divisor 80 and the new remainder 27,and apply the division lemma to get
80 = 27 x 2 + 26
We consider the new divisor 27 and the new remainder 26,and apply the division lemma to get
27 = 26 x 1 + 1
We consider the new divisor 26 and the new remainder 1,and apply the division lemma to get
26 = 1 x 26 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 989 and 25019 is 1
Notice that 1 = HCF(26,1) = HCF(27,26) = HCF(80,27) = HCF(107,80) = HCF(294,107) = HCF(989,294) = HCF(25019,989) .
