HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 1009, 7469 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 1009, 7469 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 1009, 7469 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 1009, 7469 is 1.
HCF(1009, 7469) = 1
HCF of 1009, 7469 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 1009, 7469 is 1.
Highest Common Factor of 1009,7469 is 1
Step 1: Since 7469 > 1009, we apply the division lemma to 7469 and 1009, to get
7469 = 1009 x 7 + 406
Step 2: Since the reminder 1009 ≠ 0, we apply division lemma to 406 and 1009, to get
1009 = 406 x 2 + 197
Step 3: We consider the new divisor 406 and the new remainder 197, and apply the division lemma to get
406 = 197 x 2 + 12
We consider the new divisor 197 and the new remainder 12,and apply the division lemma to get
197 = 12 x 16 + 5
We consider the new divisor 12 and the new remainder 5,and apply the division lemma to get
12 = 5 x 2 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1009 and 7469 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(12,5) = HCF(197,12) = HCF(406,197) = HCF(1009,406) = HCF(7469,1009) .
