HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 438, 93 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 438, 93 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 438, 93 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 438, 93 is 3.
HCF(438, 93) = 3
HCF of 438, 93 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 438, 93 is 3.
Highest Common Factor of 438,93 is 3
Step 1: Since 438 > 93, we apply the division lemma to 438 and 93, to get
438 = 93 x 4 + 66
Step 2: Since the reminder 93 ≠ 0, we apply division lemma to 66 and 93, to get
93 = 66 x 1 + 27
Step 3: We consider the new divisor 66 and the new remainder 27, and apply the division lemma to get
66 = 27 x 2 + 12
We consider the new divisor 27 and the new remainder 12,and apply the division lemma to get
27 = 12 x 2 + 3
We consider the new divisor 12 and the new remainder 3,and apply the division lemma to get
12 = 3 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 438 and 93 is 3
Notice that 3 = HCF(12,3) = HCF(27,12) = HCF(66,27) = HCF(93,66) = HCF(438,93) .
