HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 338, 124 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 338, 124 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 338, 124 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 338, 124 is 2.
HCF(338, 124) = 2
HCF of 338, 124 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 338, 124 is 2.
Highest Common Factor of 338,124 is 2
Step 1: Since 338 > 124, we apply the division lemma to 338 and 124, to get
338 = 124 x 2 + 90
Step 2: Since the reminder 124 ≠ 0, we apply division lemma to 90 and 124, to get
124 = 90 x 1 + 34
Step 3: We consider the new divisor 90 and the new remainder 34, and apply the division lemma to get
90 = 34 x 2 + 22
We consider the new divisor 34 and the new remainder 22,and apply the division lemma to get
34 = 22 x 1 + 12
We consider the new divisor 22 and the new remainder 12,and apply the division lemma to get
22 = 12 x 1 + 10
We consider the new divisor 12 and the new remainder 10,and apply the division lemma to get
12 = 10 x 1 + 2
We consider the new divisor 10 and the new remainder 2,and apply the division lemma to get
10 = 2 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 338 and 124 is 2
Notice that 2 = HCF(10,2) = HCF(12,10) = HCF(22,12) = HCF(34,22) = HCF(90,34) = HCF(124,90) = HCF(338,124) .
