HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 278, 518, 381 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 278, 518, 381 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 278, 518, 381 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 278, 518, 381 is 1.
HCF(278, 518, 381) = 1
HCF of 278, 518, 381 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 278, 518, 381 is 1.
Highest Common Factor of 278,518,381 is 1
Step 1: Since 518 > 278, we apply the division lemma to 518 and 278, to get
518 = 278 x 1 + 240
Step 2: Since the reminder 278 ≠ 0, we apply division lemma to 240 and 278, to get
278 = 240 x 1 + 38
Step 3: We consider the new divisor 240 and the new remainder 38, and apply the division lemma to get
240 = 38 x 6 + 12
We consider the new divisor 38 and the new remainder 12,and apply the division lemma to get
38 = 12 x 3 + 2
We consider the new divisor 12 and the new remainder 2,and apply the division lemma to get
12 = 2 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 278 and 518 is 2
Notice that 2 = HCF(12,2) = HCF(38,12) = HCF(240,38) = HCF(278,240) = HCF(518,278) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 381 > 2, we apply the division lemma to 381 and 2, to get
381 = 2 x 190 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 2 and 381 is 1
Notice that 1 = HCF(2,1) = HCF(381,2) .
