HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 509, 784, 535, 239 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 509, 784, 535, 239 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 509, 784, 535, 239 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 509, 784, 535, 239 is 1.
HCF(509, 784, 535, 239) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 509, 784, 535, 239 is 1.
Step 1: Since 784 > 509, we apply the division lemma to 784 and 509, to get
784 = 509 x 1 + 275
Step 2: Since the reminder 509 ≠ 0, we apply division lemma to 275 and 509, to get
509 = 275 x 1 + 234
Step 3: We consider the new divisor 275 and the new remainder 234, and apply the division lemma to get
275 = 234 x 1 + 41
We consider the new divisor 234 and the new remainder 41,and apply the division lemma to get
234 = 41 x 5 + 29
We consider the new divisor 41 and the new remainder 29,and apply the division lemma to get
41 = 29 x 1 + 12
We consider the new divisor 29 and the new remainder 12,and apply the division lemma to get
29 = 12 x 2 + 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 509 and 784 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(12,5) = HCF(29,12) = HCF(41,29) = HCF(234,41) = HCF(275,234) = HCF(509,275) = HCF(784,509) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 535 > 1, we apply the division lemma to 535 and 1, to get
535 = 1 x 535 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 535 is 1
Notice that 1 = HCF(535,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 239 > 1, we apply the division lemma to 239 and 1, to get
239 = 1 x 239 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 239 is 1
Notice that 1 = HCF(239,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
