HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 89, 407, 15 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 89, 407, 15 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 89, 407, 15 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 89, 407, 15 is 1.
HCF(89, 407, 15) = 1
HCF of 89, 407, 15 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 89, 407, 15 is 1.
Highest Common Factor of 89,407,15 is 1
Step 1: Since 407 > 89, we apply the division lemma to 407 and 89, to get
407 = 89 x 4 + 51
Step 2: Since the reminder 89 ≠ 0, we apply division lemma to 51 and 89, to get
89 = 51 x 1 + 38
Step 3: We consider the new divisor 51 and the new remainder 38, and apply the division lemma to get
51 = 38 x 1 + 13
We consider the new divisor 38 and the new remainder 13,and apply the division lemma to get
38 = 13 x 2 + 12
We consider the new divisor 13 and the new remainder 12,and apply the division lemma to get
13 = 12 x 1 + 1
We consider the new divisor 12 and the new remainder 1,and apply the division lemma to get
12 = 1 x 12 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 89 and 407 is 1
Notice that 1 = HCF(12,1) = HCF(13,12) = HCF(38,13) = HCF(51,38) = HCF(89,51) = HCF(407,89) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 15 > 1, we apply the division lemma to 15 and 1, to get
15 = 1 x 15 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 15 is 1
Notice that 1 = HCF(15,1) .
