HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 393, 154, 589 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 393, 154, 589 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 393, 154, 589 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 393, 154, 589 is 1.
HCF(393, 154, 589) = 1
HCF of 393, 154, 589 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 393, 154, 589 is 1.
Highest Common Factor of 393,154,589 is 1
Step 1: Since 393 > 154, we apply the division lemma to 393 and 154, to get
393 = 154 x 2 + 85
Step 2: Since the reminder 154 ≠ 0, we apply division lemma to 85 and 154, to get
154 = 85 x 1 + 69
Step 3: We consider the new divisor 85 and the new remainder 69, and apply the division lemma to get
85 = 69 x 1 + 16
We consider the new divisor 69 and the new remainder 16,and apply the division lemma to get
69 = 16 x 4 + 5
We consider the new divisor 16 and the new remainder 5,and apply the division lemma to get
16 = 5 x 3 + 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 393 and 154 is 1
Notice that 1 = HCF(5,1) = HCF(16,5) = HCF(69,16) = HCF(85,69) = HCF(154,85) = HCF(393,154) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 589 > 1, we apply the division lemma to 589 and 1, to get
589 = 1 x 589 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 589 is 1
Notice that 1 = HCF(589,1) .
