HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 338, 451, 743 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 338, 451, 743 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 338, 451, 743 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 338, 451, 743 is 1.
HCF(338, 451, 743) = 1
HCF of 338, 451, 743 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 338, 451, 743 is 1.
Highest Common Factor of 338,451,743 is 1
Step 1: Since 451 > 338, we apply the division lemma to 451 and 338, to get
451 = 338 x 1 + 113
Step 2: Since the reminder 338 ≠ 0, we apply division lemma to 113 and 338, to get
338 = 113 x 2 + 112
Step 3: We consider the new divisor 113 and the new remainder 112, and apply the division lemma to get
113 = 112 x 1 + 1
We consider the new divisor 112 and the new remainder 1, and apply the division lemma to get
112 = 1 x 112 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 338 and 451 is 1
Notice that 1 = HCF(112,1) = HCF(113,112) = HCF(338,113) = HCF(451,338) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 743 > 1, we apply the division lemma to 743 and 1, to get
743 = 1 x 743 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 743 is 1
Notice that 1 = HCF(743,1) .
