HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 784, 434, 415 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 784, 434, 415 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 784, 434, 415 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 784, 434, 415 is 1.
HCF(784, 434, 415) = 1
HCF of 784, 434, 415 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 784, 434, 415 is 1.
Highest Common Factor of 784,434,415 is 1
Step 1: Since 784 > 434, we apply the division lemma to 784 and 434, to get
784 = 434 x 1 + 350
Step 2: Since the reminder 434 ≠ 0, we apply division lemma to 350 and 434, to get
434 = 350 x 1 + 84
Step 3: We consider the new divisor 350 and the new remainder 84, and apply the division lemma to get
350 = 84 x 4 + 14
We consider the new divisor 84 and the new remainder 14, and apply the division lemma to get
84 = 14 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 14, the HCF of 784 and 434 is 14
Notice that 14 = HCF(84,14) = HCF(350,84) = HCF(434,350) = HCF(784,434) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 415 > 14, we apply the division lemma to 415 and 14, to get
415 = 14 x 29 + 9
Step 2: Since the reminder 14 ≠ 0, we apply division lemma to 9 and 14, to get
14 = 9 x 1 + 5
Step 3: We consider the new divisor 9 and the new remainder 5, and apply the division lemma to get
9 = 5 x 1 + 4
We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get
5 = 4 x 1 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 14 and 415 is 1
Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(9,5) = HCF(14,9) = HCF(415,14) .
