HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 484, 379, 666 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 484, 379, 666 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 484, 379, 666 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 484, 379, 666 is 1.
HCF(484, 379, 666) = 1
HCF of 484, 379, 666 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 484, 379, 666 is 1.
Highest Common Factor of 484,379,666 is 1
Step 1: Since 484 > 379, we apply the division lemma to 484 and 379, to get
484 = 379 x 1 + 105
Step 2: Since the reminder 379 ≠ 0, we apply division lemma to 105 and 379, to get
379 = 105 x 3 + 64
Step 3: We consider the new divisor 105 and the new remainder 64, and apply the division lemma to get
105 = 64 x 1 + 41
We consider the new divisor 64 and the new remainder 41,and apply the division lemma to get
64 = 41 x 1 + 23
We consider the new divisor 41 and the new remainder 23,and apply the division lemma to get
41 = 23 x 1 + 18
We consider the new divisor 23 and the new remainder 18,and apply the division lemma to get
23 = 18 x 1 + 5
We consider the new divisor 18 and the new remainder 5,and apply the division lemma to get
18 = 5 x 3 + 3
We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get
5 = 3 x 1 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 1
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 484 and 379 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(18,5) = HCF(23,18) = HCF(41,23) = HCF(64,41) = HCF(105,64) = HCF(379,105) = HCF(484,379) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 666 > 1, we apply the division lemma to 666 and 1, to get
666 = 1 x 666 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 666 is 1
Notice that 1 = HCF(666,1) .
