HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 410, 989 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 410, 989 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 410, 989 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 410, 989 is 1.
HCF(410, 989) = 1
HCF of 410, 989 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 410, 989 is 1.
Highest Common Factor of 410,989 is 1
Step 1: Since 989 > 410, we apply the division lemma to 989 and 410, to get
989 = 410 x 2 + 169
Step 2: Since the reminder 410 ≠ 0, we apply division lemma to 169 and 410, to get
410 = 169 x 2 + 72
Step 3: We consider the new divisor 169 and the new remainder 72, and apply the division lemma to get
169 = 72 x 2 + 25
We consider the new divisor 72 and the new remainder 25,and apply the division lemma to get
72 = 25 x 2 + 22
We consider the new divisor 25 and the new remainder 22,and apply the division lemma to get
25 = 22 x 1 + 3
We consider the new divisor 22 and the new remainder 3,and apply the division lemma to get
22 = 3 x 7 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 410 and 989 is 1
Notice that 1 = HCF(3,1) = HCF(22,3) = HCF(25,22) = HCF(72,25) = HCF(169,72) = HCF(410,169) = HCF(989,410) .
