HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 554, 11938 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 554, 11938 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 554, 11938 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 554, 11938 is 2.
HCF(554, 11938) = 2
HCF of 554, 11938 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 554, 11938 is 2.
Highest Common Factor of 554,11938 is 2
Step 1: Since 11938 > 554, we apply the division lemma to 11938 and 554, to get
11938 = 554 x 21 + 304
Step 2: Since the reminder 554 ≠ 0, we apply division lemma to 304 and 554, to get
554 = 304 x 1 + 250
Step 3: We consider the new divisor 304 and the new remainder 250, and apply the division lemma to get
304 = 250 x 1 + 54
We consider the new divisor 250 and the new remainder 54,and apply the division lemma to get
250 = 54 x 4 + 34
We consider the new divisor 54 and the new remainder 34,and apply the division lemma to get
54 = 34 x 1 + 20
We consider the new divisor 34 and the new remainder 20,and apply the division lemma to get
34 = 20 x 1 + 14
We consider the new divisor 20 and the new remainder 14,and apply the division lemma to get
20 = 14 x 1 + 6
We consider the new divisor 14 and the new remainder 6,and apply the division lemma to get
14 = 6 x 2 + 2
We consider the new divisor 6 and the new remainder 2,and apply the division lemma to get
6 = 2 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 554 and 11938 is 2
Notice that 2 = HCF(6,2) = HCF(14,6) = HCF(20,14) = HCF(34,20) = HCF(54,34) = HCF(250,54) = HCF(304,250) = HCF(554,304) = HCF(11938,554) .
