HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 448, 171, 919 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 448, 171, 919 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 448, 171, 919 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 448, 171, 919 is 1.
HCF(448, 171, 919) = 1
HCF of 448, 171, 919 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 448, 171, 919 is 1.
Highest Common Factor of 448,171,919 is 1
Step 1: Since 448 > 171, we apply the division lemma to 448 and 171, to get
448 = 171 x 2 + 106
Step 2: Since the reminder 171 ≠ 0, we apply division lemma to 106 and 171, to get
171 = 106 x 1 + 65
Step 3: We consider the new divisor 106 and the new remainder 65, and apply the division lemma to get
106 = 65 x 1 + 41
We consider the new divisor 65 and the new remainder 41,and apply the division lemma to get
65 = 41 x 1 + 24
We consider the new divisor 41 and the new remainder 24,and apply the division lemma to get
41 = 24 x 1 + 17
We consider the new divisor 24 and the new remainder 17,and apply the division lemma to get
24 = 17 x 1 + 7
We consider the new divisor 17 and the new remainder 7,and apply the division lemma to get
17 = 7 x 2 + 3
We consider the new divisor 7 and the new remainder 3,and apply the division lemma to get
7 = 3 x 2 + 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 448 and 171 is 1
Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(17,7) = HCF(24,17) = HCF(41,24) = HCF(65,41) = HCF(106,65) = HCF(171,106) = HCF(448,171) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 919 > 1, we apply the division lemma to 919 and 1, to get
919 = 1 x 919 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 919 is 1
Notice that 1 = HCF(919,1) .
