HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 408, 166, 287 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 408, 166, 287 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 408, 166, 287 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 408, 166, 287 is 1.
HCF(408, 166, 287) = 1
HCF of 408, 166, 287 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 408, 166, 287 is 1.
Highest Common Factor of 408,166,287 is 1
Step 1: Since 408 > 166, we apply the division lemma to 408 and 166, to get
408 = 166 x 2 + 76
Step 2: Since the reminder 166 ≠ 0, we apply division lemma to 76 and 166, to get
166 = 76 x 2 + 14
Step 3: We consider the new divisor 76 and the new remainder 14, and apply the division lemma to get
76 = 14 x 5 + 6
We consider the new divisor 14 and the new remainder 6,and apply the division lemma to get
14 = 6 x 2 + 2
We consider the new divisor 6 and the new remainder 2,and apply the division lemma to get
6 = 2 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 408 and 166 is 2
Notice that 2 = HCF(6,2) = HCF(14,6) = HCF(76,14) = HCF(166,76) = HCF(408,166) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 287 > 2, we apply the division lemma to 287 and 2, to get
287 = 2 x 143 + 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 287 is 1
Notice that 1 = HCF(2,1) = HCF(287,2) .
