HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 630, 568, 173 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 630, 568, 173 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 630, 568, 173 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 630, 568, 173 is 1.
HCF(630, 568, 173) = 1
HCF of 630, 568, 173 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 630, 568, 173 is 1.
Highest Common Factor of 630,568,173 is 1
Step 1: Since 630 > 568, we apply the division lemma to 630 and 568, to get
630 = 568 x 1 + 62
Step 2: Since the reminder 568 ≠ 0, we apply division lemma to 62 and 568, to get
568 = 62 x 9 + 10
Step 3: We consider the new divisor 62 and the new remainder 10, and apply the division lemma to get
62 = 10 x 6 + 2
We consider the new divisor 10 and the new remainder 2, and apply the division lemma to get
10 = 2 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 630 and 568 is 2
Notice that 2 = HCF(10,2) = HCF(62,10) = HCF(568,62) = HCF(630,568) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 173 > 2, we apply the division lemma to 173 and 2, to get
173 = 2 x 86 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 173 is 1
Notice that 1 = HCF(2,1) = HCF(173,2) .
