HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 426, 705, 538 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 426, 705, 538 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 426, 705, 538 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 426, 705, 538 is 1.
HCF(426, 705, 538) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 426, 705, 538 is 1.
Step 1: Since 705 > 426, we apply the division lemma to 705 and 426, to get
705 = 426 x 1 + 279
Step 2: Since the reminder 426 ≠ 0, we apply division lemma to 279 and 426, to get
426 = 279 x 1 + 147
Step 3: We consider the new divisor 279 and the new remainder 147, and apply the division lemma to get
279 = 147 x 1 + 132
We consider the new divisor 147 and the new remainder 132,and apply the division lemma to get
147 = 132 x 1 + 15
We consider the new divisor 132 and the new remainder 15,and apply the division lemma to get
132 = 15 x 8 + 12
We consider the new divisor 15 and the new remainder 12,and apply the division lemma to get
15 = 12 x 1 + 3
We consider the new divisor 12 and the new remainder 3,and apply the division lemma to get
12 = 3 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 426 and 705 is 3
Notice that 3 = HCF(12,3) = HCF(15,12) = HCF(132,15) = HCF(147,132) = HCF(279,147) = HCF(426,279) = HCF(705,426) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 538 > 3, we apply the division lemma to 538 and 3, to get
538 = 3 x 179 + 1
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 3 and 538 is 1
Notice that 1 = HCF(3,1) = HCF(538,3) .
Here are some samples of HCF using Euclid's Algorithm calculations.
