HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 392, 462, 543 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 392, 462, 543 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 392, 462, 543 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 392, 462, 543 is 1.
HCF(392, 462, 543) = 1
HCF of 392, 462, 543 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 392, 462, 543 is 1.
Highest Common Factor of 392,462,543 is 1
Step 1: Since 462 > 392, we apply the division lemma to 462 and 392, to get
462 = 392 x 1 + 70
Step 2: Since the reminder 392 ≠ 0, we apply division lemma to 70 and 392, to get
392 = 70 x 5 + 42
Step 3: We consider the new divisor 70 and the new remainder 42, and apply the division lemma to get
70 = 42 x 1 + 28
We consider the new divisor 42 and the new remainder 28,and apply the division lemma to get
42 = 28 x 1 + 14
We consider the new divisor 28 and the new remainder 14,and apply the division lemma to get
28 = 14 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 14, the HCF of 392 and 462 is 14
Notice that 14 = HCF(28,14) = HCF(42,28) = HCF(70,42) = HCF(392,70) = HCF(462,392) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 543 > 14, we apply the division lemma to 543 and 14, to get
543 = 14 x 38 + 11
Step 2: Since the reminder 14 ≠ 0, we apply division lemma to 11 and 14, to get
14 = 11 x 1 + 3
Step 3: We consider the new divisor 11 and the new remainder 3, and apply the division lemma to get
11 = 3 x 3 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 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 14 and 543 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(11,3) = HCF(14,11) = HCF(543,14) .
