HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 4543, 6685, 53693 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 4543, 6685, 53693 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 4543, 6685, 53693 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 4543, 6685, 53693 is 1.
HCF(4543, 6685, 53693) = 1
HCF of 4543, 6685, 53693 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 4543, 6685, 53693 is 1.
Highest Common Factor of 4543,6685,53693 is 1
Step 1: Since 6685 > 4543, we apply the division lemma to 6685 and 4543, to get
6685 = 4543 x 1 + 2142
Step 2: Since the reminder 4543 ≠ 0, we apply division lemma to 2142 and 4543, to get
4543 = 2142 x 2 + 259
Step 3: We consider the new divisor 2142 and the new remainder 259, and apply the division lemma to get
2142 = 259 x 8 + 70
We consider the new divisor 259 and the new remainder 70,and apply the division lemma to get
259 = 70 x 3 + 49
We consider the new divisor 70 and the new remainder 49,and apply the division lemma to get
70 = 49 x 1 + 21
We consider the new divisor 49 and the new remainder 21,and apply the division lemma to get
49 = 21 x 2 + 7
We consider the new divisor 21 and the new remainder 7,and apply the division lemma to get
21 = 7 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 4543 and 6685 is 7
Notice that 7 = HCF(21,7) = HCF(49,21) = HCF(70,49) = HCF(259,70) = HCF(2142,259) = HCF(4543,2142) = HCF(6685,4543) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 53693 > 7, we apply the division lemma to 53693 and 7, to get
53693 = 7 x 7670 + 3
Step 2: Since the reminder 7 ≠ 0, we apply division lemma to 3 and 7, to get
7 = 3 x 2 + 1
Step 3: 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 7 and 53693 is 1
Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(53693,7) .
