HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 9890, 7730, 47871 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 9890, 7730, 47871 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 9890, 7730, 47871 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 9890, 7730, 47871 is 1.
HCF(9890, 7730, 47871) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 9890, 7730, 47871 is 1.
Step 1: Since 9890 > 7730, we apply the division lemma to 9890 and 7730, to get
9890 = 7730 x 1 + 2160
Step 2: Since the reminder 7730 ≠ 0, we apply division lemma to 2160 and 7730, to get
7730 = 2160 x 3 + 1250
Step 3: We consider the new divisor 2160 and the new remainder 1250, and apply the division lemma to get
2160 = 1250 x 1 + 910
We consider the new divisor 1250 and the new remainder 910,and apply the division lemma to get
1250 = 910 x 1 + 340
We consider the new divisor 910 and the new remainder 340,and apply the division lemma to get
910 = 340 x 2 + 230
We consider the new divisor 340 and the new remainder 230,and apply the division lemma to get
340 = 230 x 1 + 110
We consider the new divisor 230 and the new remainder 110,and apply the division lemma to get
230 = 110 x 2 + 10
We consider the new divisor 110 and the new remainder 10,and apply the division lemma to get
110 = 10 x 11 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 10, the HCF of 9890 and 7730 is 10
Notice that 10 = HCF(110,10) = HCF(230,110) = HCF(340,230) = HCF(910,340) = HCF(1250,910) = HCF(2160,1250) = HCF(7730,2160) = HCF(9890,7730) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 47871 > 10, we apply the division lemma to 47871 and 10, to get
47871 = 10 x 4787 + 1
Step 2: Since the reminder 10 ≠ 0, we apply division lemma to 1 and 10, to get
10 = 1 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 10 and 47871 is 1
Notice that 1 = HCF(10,1) = HCF(47871,10) .
Here are some samples of HCF using Euclid's Algorithm calculations.
