HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 126, 588, 278 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 126, 588, 278 is 2 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 126, 588, 278 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 126, 588, 278 is 2.
HCF(126, 588, 278) = 2
HCF of 126, 588, 278 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 126, 588, 278 is 2.
Highest Common Factor of 126,588,278 is 2
Step 1: Since 588 > 126, we apply the division lemma to 588 and 126, to get
588 = 126 x 4 + 84
Step 2: Since the reminder 126 ≠ 0, we apply division lemma to 84 and 126, to get
126 = 84 x 1 + 42
Step 3: We consider the new divisor 84 and the new remainder 42, and apply the division lemma to get
84 = 42 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 42, the HCF of 126 and 588 is 42
Notice that 42 = HCF(84,42) = HCF(126,84) = HCF(588,126) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 278 > 42, we apply the division lemma to 278 and 42, to get
278 = 42 x 6 + 26
Step 2: Since the reminder 42 ≠ 0, we apply division lemma to 26 and 42, to get
42 = 26 x 1 + 16
Step 3: We consider the new divisor 26 and the new remainder 16, and apply the division lemma to get
26 = 16 x 1 + 10
We consider the new divisor 16 and the new remainder 10,and apply the division lemma to get
16 = 10 x 1 + 6
We consider the new divisor 10 and the new remainder 6,and apply the division lemma to get
10 = 6 x 1 + 4
We consider the new divisor 6 and the new remainder 4,and apply the division lemma to get
6 = 4 x 1 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 42 and 278 is 2
Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(10,6) = HCF(16,10) = HCF(26,16) = HCF(42,26) = HCF(278,42) .
