HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 9987, 4772 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 9987, 4772 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 9987, 4772 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 9987, 4772 is 1.
HCF(9987, 4772) = 1
HCF of 9987, 4772 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 9987, 4772 is 1.
Highest Common Factor of 9987,4772 is 1
Step 1: Since 9987 > 4772, we apply the division lemma to 9987 and 4772, to get
9987 = 4772 x 2 + 443
Step 2: Since the reminder 4772 ≠ 0, we apply division lemma to 443 and 4772, to get
4772 = 443 x 10 + 342
Step 3: We consider the new divisor 443 and the new remainder 342, and apply the division lemma to get
443 = 342 x 1 + 101
We consider the new divisor 342 and the new remainder 101,and apply the division lemma to get
342 = 101 x 3 + 39
We consider the new divisor 101 and the new remainder 39,and apply the division lemma to get
101 = 39 x 2 + 23
We consider the new divisor 39 and the new remainder 23,and apply the division lemma to get
39 = 23 x 1 + 16
We consider the new divisor 23 and the new remainder 16,and apply the division lemma to get
23 = 16 x 1 + 7
We consider the new divisor 16 and the new remainder 7,and apply the division lemma to get
16 = 7 x 2 + 2
We consider the new divisor 7 and the new remainder 2,and apply the division lemma to get
7 = 2 x 3 + 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 9987 and 4772 is 1
Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(16,7) = HCF(23,16) = HCF(39,23) = HCF(101,39) = HCF(342,101) = HCF(443,342) = HCF(4772,443) = HCF(9987,4772) .
