HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 278, 508 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 278, 508 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 278, 508 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, 508 is 2.
HCF(278, 508) = 2
HCF of 278, 508 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, 508 is 2.
Highest Common Factor of 278,508 is 2
Step 1: Since 508 > 278, we apply the division lemma to 508 and 278, to get
508 = 278 x 1 + 230
Step 2: Since the reminder 278 ≠ 0, we apply division lemma to 230 and 278, to get
278 = 230 x 1 + 48
Step 3: We consider the new divisor 230 and the new remainder 48, and apply the division lemma to get
230 = 48 x 4 + 38
We consider the new divisor 48 and the new remainder 38,and apply the division lemma to get
48 = 38 x 1 + 10
We consider the new divisor 38 and the new remainder 10,and apply the division lemma to get
38 = 10 x 3 + 8
We consider the new divisor 10 and the new remainder 8,and apply the division lemma to get
10 = 8 x 1 + 2
We consider the new divisor 8 and the new remainder 2,and apply the division lemma to get
8 = 2 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 278 and 508 is 2
Notice that 2 = HCF(8,2) = HCF(10,8) = HCF(38,10) = HCF(48,38) = HCF(230,48) = HCF(278,230) = HCF(508,278) .
