HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 579, 931, 637, 28 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 579, 931, 637, 28 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 579, 931, 637, 28 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 579, 931, 637, 28 is 1.
HCF(579, 931, 637, 28) = 1
HCF of 579, 931, 637, 28 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 579, 931, 637, 28 is 1.
Highest Common Factor of 579,931,637,28 is 1
Step 1: Since 931 > 579, we apply the division lemma to 931 and 579, to get
931 = 579 x 1 + 352
Step 2: Since the reminder 579 ≠ 0, we apply division lemma to 352 and 579, to get
579 = 352 x 1 + 227
Step 3: We consider the new divisor 352 and the new remainder 227, and apply the division lemma to get
352 = 227 x 1 + 125
We consider the new divisor 227 and the new remainder 125,and apply the division lemma to get
227 = 125 x 1 + 102
We consider the new divisor 125 and the new remainder 102,and apply the division lemma to get
125 = 102 x 1 + 23
We consider the new divisor 102 and the new remainder 23,and apply the division lemma to get
102 = 23 x 4 + 10
We consider the new divisor 23 and the new remainder 10,and apply the division lemma to get
23 = 10 x 2 + 3
We consider the new divisor 10 and the new remainder 3,and apply the division lemma to get
10 = 3 x 3 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma 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 579 and 931 is 1
Notice that 1 = HCF(3,1) = HCF(10,3) = HCF(23,10) = HCF(102,23) = HCF(125,102) = HCF(227,125) = HCF(352,227) = HCF(579,352) = HCF(931,579) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 637 > 1, we apply the division lemma to 637 and 1, to get
637 = 1 x 637 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 637 is 1
Notice that 1 = HCF(637,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 28 > 1, we apply the division lemma to 28 and 1, to get
28 = 1 x 28 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 28 is 1
Notice that 1 = HCF(28,1) .
