HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 5195, 9837, 70435 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 5195, 9837, 70435 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 5195, 9837, 70435 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 5195, 9837, 70435 is 1.
HCF(5195, 9837, 70435) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 5195, 9837, 70435 is 1.
Step 1: Since 9837 > 5195, we apply the division lemma to 9837 and 5195, to get
9837 = 5195 x 1 + 4642
Step 2: Since the reminder 5195 ≠ 0, we apply division lemma to 4642 and 5195, to get
5195 = 4642 x 1 + 553
Step 3: We consider the new divisor 4642 and the new remainder 553, and apply the division lemma to get
4642 = 553 x 8 + 218
We consider the new divisor 553 and the new remainder 218,and apply the division lemma to get
553 = 218 x 2 + 117
We consider the new divisor 218 and the new remainder 117,and apply the division lemma to get
218 = 117 x 1 + 101
We consider the new divisor 117 and the new remainder 101,and apply the division lemma to get
117 = 101 x 1 + 16
We consider the new divisor 101 and the new remainder 16,and apply the division lemma to get
101 = 16 x 6 + 5
We consider the new divisor 16 and the new remainder 5,and apply the division lemma to get
16 = 5 x 3 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 5195 and 9837 is 1
Notice that 1 = HCF(5,1) = HCF(16,5) = HCF(101,16) = HCF(117,101) = HCF(218,117) = HCF(553,218) = HCF(4642,553) = HCF(5195,4642) = HCF(9837,5195) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 70435 > 1, we apply the division lemma to 70435 and 1, to get
70435 = 1 x 70435 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 70435 is 1
Notice that 1 = HCF(70435,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
