HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 174, 664, 398, 863 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 174, 664, 398, 863 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 174, 664, 398, 863 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 174, 664, 398, 863 is 1.
HCF(174, 664, 398, 863) = 1
HCF of 174, 664, 398, 863 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 174, 664, 398, 863 is 1.
Highest Common Factor of 174,664,398,863 is 1
Step 1: Since 664 > 174, we apply the division lemma to 664 and 174, to get
664 = 174 x 3 + 142
Step 2: Since the reminder 174 ≠ 0, we apply division lemma to 142 and 174, to get
174 = 142 x 1 + 32
Step 3: We consider the new divisor 142 and the new remainder 32, and apply the division lemma to get
142 = 32 x 4 + 14
We consider the new divisor 32 and the new remainder 14,and apply the division lemma to get
32 = 14 x 2 + 4
We consider the new divisor 14 and the new remainder 4,and apply the division lemma to get
14 = 4 x 3 + 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 174 and 664 is 2
Notice that 2 = HCF(4,2) = HCF(14,4) = HCF(32,14) = HCF(142,32) = HCF(174,142) = HCF(664,174) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 398 > 2, we apply the division lemma to 398 and 2, to get
398 = 2 x 199 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 398 is 2
Notice that 2 = HCF(398,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 863 > 2, we apply the division lemma to 863 and 2, to get
863 = 2 x 431 + 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 863 is 1
Notice that 1 = HCF(2,1) = HCF(863,2) .
