HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 390, 459, 379 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 390, 459, 379 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, 459, 379 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, 459, 379 is 1.
HCF(390, 459, 379) = 1
HCF of 390, 459, 379 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, 459, 379 is 1.
Highest Common Factor of 390,459,379 is 1
Step 1: Since 459 > 390, we apply the division lemma to 459 and 390, to get
459 = 390 x 1 + 69
Step 2: Since the reminder 390 ≠ 0, we apply division lemma to 69 and 390, to get
390 = 69 x 5 + 45
Step 3: We consider the new divisor 69 and the new remainder 45, and apply the division lemma to get
69 = 45 x 1 + 24
We consider the new divisor 45 and the new remainder 24,and apply the division lemma to get
45 = 24 x 1 + 21
We consider the new divisor 24 and the new remainder 21,and apply the division lemma to get
24 = 21 x 1 + 3
We consider the new divisor 21 and the new remainder 3,and apply the division lemma to get
21 = 3 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 390 and 459 is 3
Notice that 3 = HCF(21,3) = HCF(24,21) = HCF(45,24) = HCF(69,45) = HCF(390,69) = HCF(459,390) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 379 > 3, we apply the division lemma to 379 and 3, to get
379 = 3 x 126 + 1
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 3 and 379 is 1
Notice that 1 = HCF(3,1) = HCF(379,3) .
