HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 390, 874, 459 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 390, 874, 459 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 390, 874, 459 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 390, 874, 459 is 1.
HCF(390, 874, 459) = 1
HCF of 390, 874, 459 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 390, 874, 459 is 1.
Highest Common Factor of 390,874,459 is 1
Step 1: Since 874 > 390, we apply the division lemma to 874 and 390, to get
874 = 390 x 2 + 94
Step 2: Since the reminder 390 ≠ 0, we apply division lemma to 94 and 390, to get
390 = 94 x 4 + 14
Step 3: We consider the new divisor 94 and the new remainder 14, and apply the division lemma to get
94 = 14 x 6 + 10
We consider the new divisor 14 and the new remainder 10,and apply the division lemma to get
14 = 10 x 1 + 4
We consider the new divisor 10 and the new remainder 4,and apply the division lemma to get
10 = 4 x 2 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 390 and 874 is 2
Notice that 2 = HCF(4,2) = HCF(10,4) = HCF(14,10) = HCF(94,14) = HCF(390,94) = HCF(874,390) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 459 > 2, we apply the division lemma to 459 and 2, to get
459 = 2 x 229 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 459 is 1
Notice that 1 = HCF(2,1) = HCF(459,2) .
