HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 787, 519, 330, 17 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 787, 519, 330, 17 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 787, 519, 330, 17 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 787, 519, 330, 17 is 1.
HCF(787, 519, 330, 17) = 1
HCF of 787, 519, 330, 17 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 787, 519, 330, 17 is 1.
Highest Common Factor of 787,519,330,17 is 1
Step 1: Since 787 > 519, we apply the division lemma to 787 and 519, to get
787 = 519 x 1 + 268
Step 2: Since the reminder 519 ≠ 0, we apply division lemma to 268 and 519, to get
519 = 268 x 1 + 251
Step 3: We consider the new divisor 268 and the new remainder 251, and apply the division lemma to get
268 = 251 x 1 + 17
We consider the new divisor 251 and the new remainder 17,and apply the division lemma to get
251 = 17 x 14 + 13
We consider the new divisor 17 and the new remainder 13,and apply the division lemma to get
17 = 13 x 1 + 4
We consider the new divisor 13 and the new remainder 4,and apply the division lemma to get
13 = 4 x 3 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 787 and 519 is 1
Notice that 1 = HCF(4,1) = HCF(13,4) = HCF(17,13) = HCF(251,17) = HCF(268,251) = HCF(519,268) = HCF(787,519) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 330 > 1, we apply the division lemma to 330 and 1, to get
330 = 1 x 330 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 330 is 1
Notice that 1 = HCF(330,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 17 > 1, we apply the division lemma to 17 and 1, to get
17 = 1 x 17 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 17 is 1
Notice that 1 = HCF(17,1) .
