HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 996, 863, 603, 643 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 996, 863, 603, 643 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 996, 863, 603, 643 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 996, 863, 603, 643 is 1.
HCF(996, 863, 603, 643) = 1
HCF of 996, 863, 603, 643 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 996, 863, 603, 643 is 1.
Highest Common Factor of 996,863,603,643 is 1
Step 1: Since 996 > 863, we apply the division lemma to 996 and 863, to get
996 = 863 x 1 + 133
Step 2: Since the reminder 863 ≠ 0, we apply division lemma to 133 and 863, to get
863 = 133 x 6 + 65
Step 3: We consider the new divisor 133 and the new remainder 65, and apply the division lemma to get
133 = 65 x 2 + 3
We consider the new divisor 65 and the new remainder 3,and apply the division lemma to get
65 = 3 x 21 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 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 996 and 863 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(65,3) = HCF(133,65) = HCF(863,133) = HCF(996,863) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 603 > 1, we apply the division lemma to 603 and 1, to get
603 = 1 x 603 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 603 is 1
Notice that 1 = HCF(603,1) .

Step 1: Since 643 > 1, we apply the division lemma to 643 and 1, to get
643 = 1 x 643 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 643 is 1
Notice that 1 = HCF(643,1) .
