HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 927, 438 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 927, 438 is 3 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 927, 438 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 927, 438 is 3.
HCF(927, 438) = 3
HCF of 927, 438 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 927, 438 is 3.
Highest Common Factor of 927,438 is 3
Step 1: Since 927 > 438, we apply the division lemma to 927 and 438, to get
927 = 438 x 2 + 51
Step 2: Since the reminder 438 ≠ 0, we apply division lemma to 51 and 438, to get
438 = 51 x 8 + 30
Step 3: We consider the new divisor 51 and the new remainder 30, and apply the division lemma to get
51 = 30 x 1 + 21
We consider the new divisor 30 and the new remainder 21,and apply the division lemma to get
30 = 21 x 1 + 9
We consider the new divisor 21 and the new remainder 9,and apply the division lemma to get
21 = 9 x 2 + 3
We consider the new divisor 9 and the new remainder 3,and apply the division lemma to get
9 = 3 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 927 and 438 is 3
Notice that 3 = HCF(9,3) = HCF(21,9) = HCF(30,21) = HCF(51,30) = HCF(438,51) = HCF(927,438) .
