HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 24, 591, 643 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 24, 591, 643 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 24, 591, 643 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 24, 591, 643 is 1.
HCF(24, 591, 643) = 1
HCF of 24, 591, 643 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 24, 591, 643 is 1.
Highest Common Factor of 24,591,643 is 1
Step 1: Since 591 > 24, we apply the division lemma to 591 and 24, to get
591 = 24 x 24 + 15
Step 2: Since the reminder 24 ≠ 0, we apply division lemma to 15 and 24, to get
24 = 15 x 1 + 9
Step 3: We consider the new divisor 15 and the new remainder 9, and apply the division lemma to get
15 = 9 x 1 + 6
We consider the new divisor 9 and the new remainder 6,and apply the division lemma to get
9 = 6 x 1 + 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 24 and 591 is 3
Notice that 3 = HCF(6,3) = HCF(9,6) = HCF(15,9) = HCF(24,15) = HCF(591,24) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 643 > 3, we apply the division lemma to 643 and 3, to get
643 = 3 x 214 + 1
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, 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 3 and 643 is 1
Notice that 1 = HCF(3,1) = HCF(643,3) .
