HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 30, 33, 38, 434 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 30, 33, 38, 434 is 1 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 30, 33, 38, 434 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 30, 33, 38, 434 is 1.
HCF(30, 33, 38, 434) = 1
HCF of 30, 33, 38, 434 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 30, 33, 38, 434 is 1.
Highest Common Factor of 30,33,38,434 is 1
Step 1: Since 33 > 30, we apply the division lemma to 33 and 30, to get
33 = 30 x 1 + 3
Step 2: Since the reminder 30 ≠ 0, we apply division lemma to 3 and 30, to get
30 = 3 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 30 and 33 is 3
Notice that 3 = HCF(30,3) = HCF(33,30) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 38 > 3, we apply the division lemma to 38 and 3, to get
38 = 3 x 12 + 2
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 2 and 3, to get
3 = 2 x 1 + 1
Step 3: We consider the new divisor 2 and the new remainder 1, and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 3 and 38 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(38,3) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 434 > 1, we apply the division lemma to 434 and 1, to get
434 = 1 x 434 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 434 is 1
Notice that 1 = HCF(434,1) .
