HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 961, 593, 630 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 961, 593, 630 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 961, 593, 630 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 961, 593, 630 is 1.
HCF(961, 593, 630) = 1
HCF of 961, 593, 630 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 961, 593, 630 is 1.
Highest Common Factor of 961,593,630 is 1
Step 1: Since 961 > 593, we apply the division lemma to 961 and 593, to get
961 = 593 x 1 + 368
Step 2: Since the reminder 593 ≠ 0, we apply division lemma to 368 and 593, to get
593 = 368 x 1 + 225
Step 3: We consider the new divisor 368 and the new remainder 225, and apply the division lemma to get
368 = 225 x 1 + 143
We consider the new divisor 225 and the new remainder 143,and apply the division lemma to get
225 = 143 x 1 + 82
We consider the new divisor 143 and the new remainder 82,and apply the division lemma to get
143 = 82 x 1 + 61
We consider the new divisor 82 and the new remainder 61,and apply the division lemma to get
82 = 61 x 1 + 21
We consider the new divisor 61 and the new remainder 21,and apply the division lemma to get
61 = 21 x 2 + 19
We consider the new divisor 21 and the new remainder 19,and apply the division lemma to get
21 = 19 x 1 + 2
We consider the new divisor 19 and the new remainder 2,and apply the division lemma to get
19 = 2 x 9 + 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 961 and 593 is 1
Notice that 1 = HCF(2,1) = HCF(19,2) = HCF(21,19) = HCF(61,21) = HCF(82,61) = HCF(143,82) = HCF(225,143) = HCF(368,225) = HCF(593,368) = HCF(961,593) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 630 > 1, we apply the division lemma to 630 and 1, to get
630 = 1 x 630 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 630 is 1
Notice that 1 = HCF(630,1) .
