HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 309, 429, 466, 793 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 309, 429, 466, 793 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 309, 429, 466, 793 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 309, 429, 466, 793 is 1.
HCF(309, 429, 466, 793) = 1
HCF of 309, 429, 466, 793 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 309, 429, 466, 793 is 1.
Highest Common Factor of 309,429,466,793 is 1
Step 1: Since 429 > 309, we apply the division lemma to 429 and 309, to get
429 = 309 x 1 + 120
Step 2: Since the reminder 309 ≠ 0, we apply division lemma to 120 and 309, to get
309 = 120 x 2 + 69
Step 3: We consider the new divisor 120 and the new remainder 69, and apply the division lemma to get
120 = 69 x 1 + 51
We consider the new divisor 69 and the new remainder 51,and apply the division lemma to get
69 = 51 x 1 + 18
We consider the new divisor 51 and the new remainder 18,and apply the division lemma to get
51 = 18 x 2 + 15
We consider the new divisor 18 and the new remainder 15,and apply the division lemma to get
18 = 15 x 1 + 3
We consider the new divisor 15 and the new remainder 3,and apply the division lemma to get
15 = 3 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 309 and 429 is 3
Notice that 3 = HCF(15,3) = HCF(18,15) = HCF(51,18) = HCF(69,51) = HCF(120,69) = HCF(309,120) = HCF(429,309) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 466 > 3, we apply the division lemma to 466 and 3, to get
466 = 3 x 155 + 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 466 is 1
Notice that 1 = HCF(3,1) = HCF(466,3) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 793 > 1, we apply the division lemma to 793 and 1, to get
793 = 1 x 793 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 793 is 1
Notice that 1 = HCF(793,1) .
