HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 407, 998, 402, 23 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 407, 998, 402, 23 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 407, 998, 402, 23 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 407, 998, 402, 23 is 1.
HCF(407, 998, 402, 23) = 1
HCF of 407, 998, 402, 23 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 407, 998, 402, 23 is 1.
Highest Common Factor of 407,998,402,23 is 1
Step 1: Since 998 > 407, we apply the division lemma to 998 and 407, to get
998 = 407 x 2 + 184
Step 2: Since the reminder 407 ≠ 0, we apply division lemma to 184 and 407, to get
407 = 184 x 2 + 39
Step 3: We consider the new divisor 184 and the new remainder 39, and apply the division lemma to get
184 = 39 x 4 + 28
We consider the new divisor 39 and the new remainder 28,and apply the division lemma to get
39 = 28 x 1 + 11
We consider the new divisor 28 and the new remainder 11,and apply the division lemma to get
28 = 11 x 2 + 6
We consider the new divisor 11 and the new remainder 6,and apply the division lemma to get
11 = 6 x 1 + 5
We consider the new divisor 6 and the new remainder 5,and apply the division lemma to get
6 = 5 x 1 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 407 and 998 is 1
Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(11,6) = HCF(28,11) = HCF(39,28) = HCF(184,39) = HCF(407,184) = HCF(998,407) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 402 > 1, we apply the division lemma to 402 and 1, to get
402 = 1 x 402 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 402 is 1
Notice that 1 = HCF(402,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 23 > 1, we apply the division lemma to 23 and 1, to get
23 = 1 x 23 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 23 is 1
Notice that 1 = HCF(23,1) .
