HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 643, 472, 24, 609 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 643, 472, 24, 609 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 643, 472, 24, 609 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 643, 472, 24, 609 is 1.
HCF(643, 472, 24, 609) = 1
HCF of 643, 472, 24, 609 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 643, 472, 24, 609 is 1.
Highest Common Factor of 643,472,24,609 is 1
Step 1: Since 643 > 472, we apply the division lemma to 643 and 472, to get
643 = 472 x 1 + 171
Step 2: Since the reminder 472 ≠ 0, we apply division lemma to 171 and 472, to get
472 = 171 x 2 + 130
Step 3: We consider the new divisor 171 and the new remainder 130, and apply the division lemma to get
171 = 130 x 1 + 41
We consider the new divisor 130 and the new remainder 41,and apply the division lemma to get
130 = 41 x 3 + 7
We consider the new divisor 41 and the new remainder 7,and apply the division lemma to get
41 = 7 x 5 + 6
We consider the new divisor 7 and the new remainder 6,and apply the division lemma to get
7 = 6 x 1 + 1
We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 643 and 472 is 1
Notice that 1 = HCF(6,1) = HCF(7,6) = HCF(41,7) = HCF(130,41) = HCF(171,130) = HCF(472,171) = HCF(643,472) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 24 > 1, we apply the division lemma to 24 and 1, to get
24 = 1 x 24 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 24 is 1
Notice that 1 = HCF(24,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 609 > 1, we apply the division lemma to 609 and 1, to get
609 = 1 x 609 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 609 is 1
Notice that 1 = HCF(609,1) .
