HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 419, 240, 30 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 419, 240, 30 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 419, 240, 30 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 419, 240, 30 is 1.
HCF(419, 240, 30) = 1
HCF of 419, 240, 30 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 419, 240, 30 is 1.
Highest Common Factor of 419,240,30 is 1
Step 1: Since 419 > 240, we apply the division lemma to 419 and 240, to get
419 = 240 x 1 + 179
Step 2: Since the reminder 240 ≠ 0, we apply division lemma to 179 and 240, to get
240 = 179 x 1 + 61
Step 3: We consider the new divisor 179 and the new remainder 61, and apply the division lemma to get
179 = 61 x 2 + 57
We consider the new divisor 61 and the new remainder 57,and apply the division lemma to get
61 = 57 x 1 + 4
We consider the new divisor 57 and the new remainder 4,and apply the division lemma to get
57 = 4 x 14 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 419 and 240 is 1
Notice that 1 = HCF(4,1) = HCF(57,4) = HCF(61,57) = HCF(179,61) = HCF(240,179) = HCF(419,240) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 30 > 1, we apply the division lemma to 30 and 1, to get
30 = 1 x 30 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 30 is 1
Notice that 1 = HCF(30,1) .
