HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 628, 493, 593 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 628, 493, 593 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 628, 493, 593 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 628, 493, 593 is 1.
HCF(628, 493, 593) = 1
HCF of 628, 493, 593 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 628, 493, 593 is 1.
Highest Common Factor of 628,493,593 is 1
Step 1: Since 628 > 493, we apply the division lemma to 628 and 493, to get
628 = 493 x 1 + 135
Step 2: Since the reminder 493 ≠ 0, we apply division lemma to 135 and 493, to get
493 = 135 x 3 + 88
Step 3: We consider the new divisor 135 and the new remainder 88, and apply the division lemma to get
135 = 88 x 1 + 47
We consider the new divisor 88 and the new remainder 47,and apply the division lemma to get
88 = 47 x 1 + 41
We consider the new divisor 47 and the new remainder 41,and apply the division lemma to get
47 = 41 x 1 + 6
We consider the new divisor 41 and the new remainder 6,and apply the division lemma to get
41 = 6 x 6 + 5
We consider the new divisor 6 and the new remainder 5,and apply the division lemma to get
6 = 5 x 1 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 628 and 493 is 1
Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(41,6) = HCF(47,41) = HCF(88,47) = HCF(135,88) = HCF(493,135) = HCF(628,493) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 593 > 1, we apply the division lemma to 593 and 1, to get
593 = 1 x 593 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 593 is 1
Notice that 1 = HCF(593,1) .
