HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 9071, 2685, 42102 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 9071, 2685, 42102 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 9071, 2685, 42102 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 9071, 2685, 42102 is 1.
HCF(9071, 2685, 42102) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 9071, 2685, 42102 is 1.
Step 1: Since 9071 > 2685, we apply the division lemma to 9071 and 2685, to get
9071 = 2685 x 3 + 1016
Step 2: Since the reminder 2685 ≠ 0, we apply division lemma to 1016 and 2685, to get
2685 = 1016 x 2 + 653
Step 3: We consider the new divisor 1016 and the new remainder 653, and apply the division lemma to get
1016 = 653 x 1 + 363
We consider the new divisor 653 and the new remainder 363,and apply the division lemma to get
653 = 363 x 1 + 290
We consider the new divisor 363 and the new remainder 290,and apply the division lemma to get
363 = 290 x 1 + 73
We consider the new divisor 290 and the new remainder 73,and apply the division lemma to get
290 = 73 x 3 + 71
We consider the new divisor 73 and the new remainder 71,and apply the division lemma to get
73 = 71 x 1 + 2
We consider the new divisor 71 and the new remainder 2,and apply the division lemma to get
71 = 2 x 35 + 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 9071 and 2685 is 1
Notice that 1 = HCF(2,1) = HCF(71,2) = HCF(73,71) = HCF(290,73) = HCF(363,290) = HCF(653,363) = HCF(1016,653) = HCF(2685,1016) = HCF(9071,2685) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 42102 > 1, we apply the division lemma to 42102 and 1, to get
42102 = 1 x 42102 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 42102 is 1
Notice that 1 = HCF(42102,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
