HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 343, 795, 970, 53 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 343, 795, 970, 53 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 343, 795, 970, 53 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 343, 795, 970, 53 is 1.
HCF(343, 795, 970, 53) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 343, 795, 970, 53 is 1.
Step 1: Since 795 > 343, we apply the division lemma to 795 and 343, to get
795 = 343 x 2 + 109
Step 2: Since the reminder 343 ≠ 0, we apply division lemma to 109 and 343, to get
343 = 109 x 3 + 16
Step 3: We consider the new divisor 109 and the new remainder 16, and apply the division lemma to get
109 = 16 x 6 + 13
We consider the new divisor 16 and the new remainder 13,and apply the division lemma to get
16 = 13 x 1 + 3
We consider the new divisor 13 and the new remainder 3,and apply the division lemma to get
13 = 3 x 4 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 343 and 795 is 1
Notice that 1 = HCF(3,1) = HCF(13,3) = HCF(16,13) = HCF(109,16) = HCF(343,109) = HCF(795,343) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 970 > 1, we apply the division lemma to 970 and 1, to get
970 = 1 x 970 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 970 is 1
Notice that 1 = HCF(970,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 53 > 1, we apply the division lemma to 53 and 1, to get
53 = 1 x 53 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 53 is 1
Notice that 1 = HCF(53,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
