HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 494, 353, 830, 26 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 494, 353, 830, 26 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 494, 353, 830, 26 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 494, 353, 830, 26 is 1.
HCF(494, 353, 830, 26) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 494, 353, 830, 26 is 1.
Step 1: Since 494 > 353, we apply the division lemma to 494 and 353, to get
494 = 353 x 1 + 141
Step 2: Since the reminder 353 ≠ 0, we apply division lemma to 141 and 353, to get
353 = 141 x 2 + 71
Step 3: We consider the new divisor 141 and the new remainder 71, and apply the division lemma to get
141 = 71 x 1 + 70
We consider the new divisor 71 and the new remainder 70,and apply the division lemma to get
71 = 70 x 1 + 1
We consider the new divisor 70 and the new remainder 1,and apply the division lemma to get
70 = 1 x 70 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 494 and 353 is 1
Notice that 1 = HCF(70,1) = HCF(71,70) = HCF(141,71) = HCF(353,141) = HCF(494,353) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 830 > 1, we apply the division lemma to 830 and 1, to get
830 = 1 x 830 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 830 is 1
Notice that 1 = HCF(830,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 26 > 1, we apply the division lemma to 26 and 1, to get
26 = 1 x 26 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 26 is 1
Notice that 1 = HCF(26,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
