HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 860, 520, 32, 509 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 860, 520, 32, 509 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 860, 520, 32, 509 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 860, 520, 32, 509 is 1.
HCF(860, 520, 32, 509) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 860, 520, 32, 509 is 1.
Step 1: Since 860 > 520, we apply the division lemma to 860 and 520, to get
860 = 520 x 1 + 340
Step 2: Since the reminder 520 ≠ 0, we apply division lemma to 340 and 520, to get
520 = 340 x 1 + 180
Step 3: We consider the new divisor 340 and the new remainder 180, and apply the division lemma to get
340 = 180 x 1 + 160
We consider the new divisor 180 and the new remainder 160,and apply the division lemma to get
180 = 160 x 1 + 20
We consider the new divisor 160 and the new remainder 20,and apply the division lemma to get
160 = 20 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 20, the HCF of 860 and 520 is 20
Notice that 20 = HCF(160,20) = HCF(180,160) = HCF(340,180) = HCF(520,340) = HCF(860,520) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 32 > 20, we apply the division lemma to 32 and 20, to get
32 = 20 x 1 + 12
Step 2: Since the reminder 20 ≠ 0, we apply division lemma to 12 and 20, to get
20 = 12 x 1 + 8
Step 3: We consider the new divisor 12 and the new remainder 8, and apply the division lemma to get
12 = 8 x 1 + 4
We consider the new divisor 8 and the new remainder 4, and apply the division lemma to get
8 = 4 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 20 and 32 is 4
Notice that 4 = HCF(8,4) = HCF(12,8) = HCF(20,12) = HCF(32,20) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 509 > 4, we apply the division lemma to 509 and 4, to get
509 = 4 x 127 + 1
Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 1 and 4, 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 4 and 509 is 1
Notice that 1 = HCF(4,1) = HCF(509,4) .
Here are some samples of HCF using Euclid's Algorithm calculations.
