HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 813, 600, 738, 77 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 813, 600, 738, 77 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, 600, 738, 77 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, 600, 738, 77 is 1.
HCF(813, 600, 738, 77) = 1
HCF of 813, 600, 738, 77 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, 600, 738, 77 is 1.
Highest Common Factor of 813,600,738,77 is 1
Step 1: Since 813 > 600, we apply the division lemma to 813 and 600, to get
813 = 600 x 1 + 213
Step 2: Since the reminder 600 ≠ 0, we apply division lemma to 213 and 600, to get
600 = 213 x 2 + 174
Step 3: We consider the new divisor 213 and the new remainder 174, and apply the division lemma to get
213 = 174 x 1 + 39
We consider the new divisor 174 and the new remainder 39,and apply the division lemma to get
174 = 39 x 4 + 18
We consider the new divisor 39 and the new remainder 18,and apply the division lemma to get
39 = 18 x 2 + 3
We consider the new divisor 18 and the new remainder 3,and apply the division lemma to get
18 = 3 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 813 and 600 is 3
Notice that 3 = HCF(18,3) = HCF(39,18) = HCF(174,39) = HCF(213,174) = HCF(600,213) = HCF(813,600) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 738 > 3, we apply the division lemma to 738 and 3, to get
738 = 3 x 246 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 738 is 3
Notice that 3 = HCF(738,3) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 77 > 3, we apply the division lemma to 77 and 3, to get
77 = 3 x 25 + 2
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 2 and 3, to get
3 = 2 x 1 + 1
Step 3: 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 3 and 77 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(77,3) .
