HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 7338, 7120, 53971 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 7338, 7120, 53971 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 7338, 7120, 53971 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 7338, 7120, 53971 is 1.
HCF(7338, 7120, 53971) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 7338, 7120, 53971 is 1.
Step 1: Since 7338 > 7120, we apply the division lemma to 7338 and 7120, to get
7338 = 7120 x 1 + 218
Step 2: Since the reminder 7120 ≠ 0, we apply division lemma to 218 and 7120, to get
7120 = 218 x 32 + 144
Step 3: We consider the new divisor 218 and the new remainder 144, and apply the division lemma to get
218 = 144 x 1 + 74
We consider the new divisor 144 and the new remainder 74,and apply the division lemma to get
144 = 74 x 1 + 70
We consider the new divisor 74 and the new remainder 70,and apply the division lemma to get
74 = 70 x 1 + 4
We consider the new divisor 70 and the new remainder 4,and apply the division lemma to get
70 = 4 x 17 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 7338 and 7120 is 2
Notice that 2 = HCF(4,2) = HCF(70,4) = HCF(74,70) = HCF(144,74) = HCF(218,144) = HCF(7120,218) = HCF(7338,7120) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 53971 > 2, we apply the division lemma to 53971 and 2, to get
53971 = 2 x 26985 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 53971 is 1
Notice that 1 = HCF(2,1) = HCF(53971,2) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?
