HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 397, 154, 510 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 397, 154, 510 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 397, 154, 510 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 397, 154, 510 is 1.
HCF(397, 154, 510) = 1
HCF of 397, 154, 510 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 397, 154, 510 is 1.
Highest Common Factor of 397,154,510 is 1
Step 1: Since 397 > 154, we apply the division lemma to 397 and 154, to get
397 = 154 x 2 + 89
Step 2: Since the reminder 154 ≠ 0, we apply division lemma to 89 and 154, to get
154 = 89 x 1 + 65
Step 3: We consider the new divisor 89 and the new remainder 65, and apply the division lemma to get
89 = 65 x 1 + 24
We consider the new divisor 65 and the new remainder 24,and apply the division lemma to get
65 = 24 x 2 + 17
We consider the new divisor 24 and the new remainder 17,and apply the division lemma to get
24 = 17 x 1 + 7
We consider the new divisor 17 and the new remainder 7,and apply the division lemma to get
17 = 7 x 2 + 3
We consider the new divisor 7 and the new remainder 3,and apply the division lemma to get
7 = 3 x 2 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 397 and 154 is 1
Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(17,7) = HCF(24,17) = HCF(65,24) = HCF(89,65) = HCF(154,89) = HCF(397,154) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 510 > 1, we apply the division lemma to 510 and 1, to get
510 = 1 x 510 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 510 is 1
Notice that 1 = HCF(510,1) .
