HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 549, 558, 24 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 549, 558, 24 is 3 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 549, 558, 24 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 549, 558, 24 is 3.
HCF(549, 558, 24) = 3
HCF of 549, 558, 24 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 549, 558, 24 is 3.
Highest Common Factor of 549,558,24 is 3
Step 1: Since 558 > 549, we apply the division lemma to 558 and 549, to get
558 = 549 x 1 + 9
Step 2: Since the reminder 549 ≠ 0, we apply division lemma to 9 and 549, to get
549 = 9 x 61 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 9, the HCF of 549 and 558 is 9
Notice that 9 = HCF(549,9) = HCF(558,549) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 24 > 9, we apply the division lemma to 24 and 9, to get
24 = 9 x 2 + 6
Step 2: Since the reminder 9 ≠ 0, we apply division lemma to 6 and 9, to get
9 = 6 x 1 + 3
Step 3: We consider the new divisor 6 and the new remainder 3, and apply the division lemma to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 9 and 24 is 3
Notice that 3 = HCF(6,3) = HCF(9,6) = HCF(24,9) .
