HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 813, 753, 70 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 813, 753, 70 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 813, 753, 70 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 813, 753, 70 is 1.
HCF(813, 753, 70) = 1
HCF of 813, 753, 70 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 813, 753, 70 is 1.
Highest Common Factor of 813,753,70 is 1
Step 1: Since 813 > 753, we apply the division lemma to 813 and 753, to get
813 = 753 x 1 + 60
Step 2: Since the reminder 753 ≠ 0, we apply division lemma to 60 and 753, to get
753 = 60 x 12 + 33
Step 3: We consider the new divisor 60 and the new remainder 33, and apply the division lemma to get
60 = 33 x 1 + 27
We consider the new divisor 33 and the new remainder 27,and apply the division lemma to get
33 = 27 x 1 + 6
We consider the new divisor 27 and the new remainder 6,and apply the division lemma to get
27 = 6 x 4 + 3
We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 813 and 753 is 3
Notice that 3 = HCF(6,3) = HCF(27,6) = HCF(33,27) = HCF(60,33) = HCF(753,60) = HCF(813,753) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 70 > 3, we apply the division lemma to 70 and 3, to get
70 = 3 x 23 + 1
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, 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 3 and 70 is 1
Notice that 1 = HCF(3,1) = HCF(70,3) .
