HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 6387, 990 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 6387, 990 is 3 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 6387, 990 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 6387, 990 is 3.
HCF(6387, 990) = 3
HCF of 6387, 990 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 6387, 990 is 3.
Highest Common Factor of 6387,990 is 3
Step 1: Since 6387 > 990, we apply the division lemma to 6387 and 990, to get
6387 = 990 x 6 + 447
Step 2: Since the reminder 990 ≠ 0, we apply division lemma to 447 and 990, to get
990 = 447 x 2 + 96
Step 3: We consider the new divisor 447 and the new remainder 96, and apply the division lemma to get
447 = 96 x 4 + 63
We consider the new divisor 96 and the new remainder 63,and apply the division lemma to get
96 = 63 x 1 + 33
We consider the new divisor 63 and the new remainder 33,and apply the division lemma to get
63 = 33 x 1 + 30
We consider the new divisor 33 and the new remainder 30,and apply the division lemma to get
33 = 30 x 1 + 3
We consider the new divisor 30 and the new remainder 3,and apply the division lemma to get
30 = 3 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 6387 and 990 is 3
Notice that 3 = HCF(30,3) = HCF(33,30) = HCF(63,33) = HCF(96,63) = HCF(447,96) = HCF(990,447) = HCF(6387,990) .
