HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 96, 31, 84, 643 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 96, 31, 84, 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 96, 31, 84, 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 96, 31, 84, 643 is 1.
HCF(96, 31, 84, 643) = 1
HCF of 96, 31, 84, 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 96, 31, 84, 643 is 1.
Highest Common Factor of 96,31,84,643 is 1
Step 1: Since 96 > 31, we apply the division lemma to 96 and 31, to get
96 = 31 x 3 + 3
Step 2: Since the reminder 31 ≠ 0, we apply division lemma to 3 and 31, to get
31 = 3 x 10 + 1
Step 3: We consider the new divisor 3 and the new remainder 1, and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 96 and 31 is 1
Notice that 1 = HCF(3,1) = HCF(31,3) = HCF(96,31) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 84 > 1, we apply the division lemma to 84 and 1, to get
84 = 1 x 84 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 84 is 1
Notice that 1 = HCF(84,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
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) .
