HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 665, 431, 306 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 665, 431, 306 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 665, 431, 306 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 665, 431, 306 is 1.
HCF(665, 431, 306) = 1
HCF of 665, 431, 306 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 665, 431, 306 is 1.
Highest Common Factor of 665,431,306 is 1
Step 1: Since 665 > 431, we apply the division lemma to 665 and 431, to get
665 = 431 x 1 + 234
Step 2: Since the reminder 431 ≠ 0, we apply division lemma to 234 and 431, to get
431 = 234 x 1 + 197
Step 3: We consider the new divisor 234 and the new remainder 197, and apply the division lemma to get
234 = 197 x 1 + 37
We consider the new divisor 197 and the new remainder 37,and apply the division lemma to get
197 = 37 x 5 + 12
We consider the new divisor 37 and the new remainder 12,and apply the division lemma to get
37 = 12 x 3 + 1
We consider the new divisor 12 and the new remainder 1,and apply the division lemma to get
12 = 1 x 12 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 665 and 431 is 1
Notice that 1 = HCF(12,1) = HCF(37,12) = HCF(197,37) = HCF(234,197) = HCF(431,234) = HCF(665,431) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 306 > 1, we apply the division lemma to 306 and 1, to get
306 = 1 x 306 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 306 is 1
Notice that 1 = HCF(306,1) .
