HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 521, 144, 573, 34 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 521, 144, 573, 34 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 521, 144, 573, 34 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 521, 144, 573, 34 is 1.
HCF(521, 144, 573, 34) = 1
HCF of 521, 144, 573, 34 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 521, 144, 573, 34 is 1.
Highest Common Factor of 521,144,573,34 is 1
Step 1: Since 521 > 144, we apply the division lemma to 521 and 144, to get
521 = 144 x 3 + 89
Step 2: Since the reminder 144 ≠ 0, we apply division lemma to 89 and 144, to get
144 = 89 x 1 + 55
Step 3: We consider the new divisor 89 and the new remainder 55, and apply the division lemma to get
89 = 55 x 1 + 34
We consider the new divisor 55 and the new remainder 34,and apply the division lemma to get
55 = 34 x 1 + 21
We consider the new divisor 34 and the new remainder 21,and apply the division lemma to get
34 = 21 x 1 + 13
We consider the new divisor 21 and the new remainder 13,and apply the division lemma to get
21 = 13 x 1 + 8
We consider the new divisor 13 and the new remainder 8,and apply the division lemma to get
13 = 8 x 1 + 5
We consider the new divisor 8 and the new remainder 5,and apply the division lemma to get
8 = 5 x 1 + 3
We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get
5 = 3 x 1 + 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 521 and 144 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(8,5) = HCF(13,8) = HCF(21,13) = HCF(34,21) = HCF(55,34) = HCF(89,55) = HCF(144,89) = HCF(521,144) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 573 > 1, we apply the division lemma to 573 and 1, to get
573 = 1 x 573 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 573 is 1
Notice that 1 = HCF(573,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 34 > 1, we apply the division lemma to 34 and 1, to get
34 = 1 x 34 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 34 is 1
Notice that 1 = HCF(34,1) .
