HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 210, 968, 813 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 210, 968, 813 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 210, 968, 813 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 210, 968, 813 is 1.
HCF(210, 968, 813) = 1
HCF of 210, 968, 813 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 210, 968, 813 is 1.
Highest Common Factor of 210,968,813 is 1
Step 1: Since 968 > 210, we apply the division lemma to 968 and 210, to get
968 = 210 x 4 + 128
Step 2: Since the reminder 210 ≠ 0, we apply division lemma to 128 and 210, to get
210 = 128 x 1 + 82
Step 3: We consider the new divisor 128 and the new remainder 82, and apply the division lemma to get
128 = 82 x 1 + 46
We consider the new divisor 82 and the new remainder 46,and apply the division lemma to get
82 = 46 x 1 + 36
We consider the new divisor 46 and the new remainder 36,and apply the division lemma to get
46 = 36 x 1 + 10
We consider the new divisor 36 and the new remainder 10,and apply the division lemma to get
36 = 10 x 3 + 6
We consider the new divisor 10 and the new remainder 6,and apply the division lemma to get
10 = 6 x 1 + 4
We consider the new divisor 6 and the new remainder 4,and apply the division lemma to get
6 = 4 x 1 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 210 and 968 is 2
Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(10,6) = HCF(36,10) = HCF(46,36) = HCF(82,46) = HCF(128,82) = HCF(210,128) = HCF(968,210) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 813 > 2, we apply the division lemma to 813 and 2, to get
813 = 2 x 406 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 813 is 1
Notice that 1 = HCF(2,1) = HCF(813,2) .
