HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 784, 229, 439, 72 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 784, 229, 439, 72 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, 229, 439, 72 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, 229, 439, 72 is 1.
HCF(784, 229, 439, 72) = 1
HCF of 784, 229, 439, 72 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, 229, 439, 72 is 1.
Highest Common Factor of 784,229,439,72 is 1
Step 1: Since 784 > 229, we apply the division lemma to 784 and 229, to get
784 = 229 x 3 + 97
Step 2: Since the reminder 229 ≠ 0, we apply division lemma to 97 and 229, to get
229 = 97 x 2 + 35
Step 3: We consider the new divisor 97 and the new remainder 35, and apply the division lemma to get
97 = 35 x 2 + 27
We consider the new divisor 35 and the new remainder 27,and apply the division lemma to get
35 = 27 x 1 + 8
We consider the new divisor 27 and the new remainder 8,and apply the division lemma to get
27 = 8 x 3 + 3
We consider the new divisor 8 and the new remainder 3,and apply the division lemma to get
8 = 3 x 2 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 1
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 784 and 229 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(8,3) = HCF(27,8) = HCF(35,27) = HCF(97,35) = HCF(229,97) = HCF(784,229) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 439 > 1, we apply the division lemma to 439 and 1, to get
439 = 1 x 439 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 439 is 1
Notice that 1 = HCF(439,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 72 > 1, we apply the division lemma to 72 and 1, to get
72 = 1 x 72 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 72 is 1
Notice that 1 = HCF(72,1) .
