HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 459, 178, 942, 464 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 459, 178, 942, 464 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 459, 178, 942, 464 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 459, 178, 942, 464 is 1.
HCF(459, 178, 942, 464) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 459, 178, 942, 464 is 1.
Step 1: Since 459 > 178, we apply the division lemma to 459 and 178, to get
459 = 178 x 2 + 103
Step 2: Since the reminder 178 ≠ 0, we apply division lemma to 103 and 178, to get
178 = 103 x 1 + 75
Step 3: We consider the new divisor 103 and the new remainder 75, and apply the division lemma to get
103 = 75 x 1 + 28
We consider the new divisor 75 and the new remainder 28,and apply the division lemma to get
75 = 28 x 2 + 19
We consider the new divisor 28 and the new remainder 19,and apply the division lemma to get
28 = 19 x 1 + 9
We consider the new divisor 19 and the new remainder 9,and apply the division lemma to get
19 = 9 x 2 + 1
We consider the new divisor 9 and the new remainder 1,and apply the division lemma to get
9 = 1 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 459 and 178 is 1
Notice that 1 = HCF(9,1) = HCF(19,9) = HCF(28,19) = HCF(75,28) = HCF(103,75) = HCF(178,103) = HCF(459,178) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 942 > 1, we apply the division lemma to 942 and 1, to get
942 = 1 x 942 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 942 is 1
Notice that 1 = HCF(942,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 464 > 1, we apply the division lemma to 464 and 1, to get
464 = 1 x 464 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 464 is 1
Notice that 1 = HCF(464,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
