HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 943, 784, 169 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 943, 784, 169 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 943, 784, 169 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 943, 784, 169 is 1.
HCF(943, 784, 169) = 1
HCF of 943, 784, 169 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 943, 784, 169 is 1.
Highest Common Factor of 943,784,169 is 1
Step 1: Since 943 > 784, we apply the division lemma to 943 and 784, to get
943 = 784 x 1 + 159
Step 2: Since the reminder 784 ≠ 0, we apply division lemma to 159 and 784, to get
784 = 159 x 4 + 148
Step 3: We consider the new divisor 159 and the new remainder 148, and apply the division lemma to get
159 = 148 x 1 + 11
We consider the new divisor 148 and the new remainder 11,and apply the division lemma to get
148 = 11 x 13 + 5
We consider the new divisor 11 and the new remainder 5,and apply the division lemma to get
11 = 5 x 2 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 943 and 784 is 1
Notice that 1 = HCF(5,1) = HCF(11,5) = HCF(148,11) = HCF(159,148) = HCF(784,159) = HCF(943,784) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 169 > 1, we apply the division lemma to 169 and 1, to get
169 = 1 x 169 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 169 is 1
Notice that 1 = HCF(169,1) .
