HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 8408, 915 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 8408, 915 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 8408, 915 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 8408, 915 is 1.
HCF(8408, 915) = 1
HCF of 8408, 915 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 8408, 915 is 1.
Highest Common Factor of 8408,915 is 1
Step 1: Since 8408 > 915, we apply the division lemma to 8408 and 915, to get
8408 = 915 x 9 + 173
Step 2: Since the reminder 915 ≠ 0, we apply division lemma to 173 and 915, to get
915 = 173 x 5 + 50
Step 3: We consider the new divisor 173 and the new remainder 50, and apply the division lemma to get
173 = 50 x 3 + 23
We consider the new divisor 50 and the new remainder 23,and apply the division lemma to get
50 = 23 x 2 + 4
We consider the new divisor 23 and the new remainder 4,and apply the division lemma to get
23 = 4 x 5 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 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 8408 and 915 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(23,4) = HCF(50,23) = HCF(173,50) = HCF(915,173) = HCF(8408,915) .
