HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 407, 285, 951, 23 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 407, 285, 951, 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, 285, 951, 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, 285, 951, 23 is 1.
HCF(407, 285, 951, 23) = 1
HCF of 407, 285, 951, 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, 285, 951, 23 is 1.
Highest Common Factor of 407,285,951,23 is 1
Step 1: Since 407 > 285, we apply the division lemma to 407 and 285, to get
407 = 285 x 1 + 122
Step 2: Since the reminder 285 ≠ 0, we apply division lemma to 122 and 285, to get
285 = 122 x 2 + 41
Step 3: We consider the new divisor 122 and the new remainder 41, and apply the division lemma to get
122 = 41 x 2 + 40
We consider the new divisor 41 and the new remainder 40,and apply the division lemma to get
41 = 40 x 1 + 1
We consider the new divisor 40 and the new remainder 1,and apply the division lemma to get
40 = 1 x 40 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 407 and 285 is 1
Notice that 1 = HCF(40,1) = HCF(41,40) = HCF(122,41) = HCF(285,122) = HCF(407,285) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 951 > 1, we apply the division lemma to 951 and 1, to get
951 = 1 x 951 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 951 is 1
Notice that 1 = HCF(951,1) .
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) .
