HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 615, 394, 512 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 615, 394, 512 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 615, 394, 512 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 615, 394, 512 is 1.
HCF(615, 394, 512) = 1
HCF of 615, 394, 512 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 615, 394, 512 is 1.
Highest Common Factor of 615,394,512 is 1
Step 1: Since 615 > 394, we apply the division lemma to 615 and 394, to get
615 = 394 x 1 + 221
Step 2: Since the reminder 394 ≠ 0, we apply division lemma to 221 and 394, to get
394 = 221 x 1 + 173
Step 3: We consider the new divisor 221 and the new remainder 173, and apply the division lemma to get
221 = 173 x 1 + 48
We consider the new divisor 173 and the new remainder 48,and apply the division lemma to get
173 = 48 x 3 + 29
We consider the new divisor 48 and the new remainder 29,and apply the division lemma to get
48 = 29 x 1 + 19
We consider the new divisor 29 and the new remainder 19,and apply the division lemma to get
29 = 19 x 1 + 10
We consider the new divisor 19 and the new remainder 10,and apply the division lemma to get
19 = 10 x 1 + 9
We consider the new divisor 10 and the new remainder 9,and apply the division lemma to get
10 = 9 x 1 + 1
We consider the new divisor 9 and the new remainder 1,and apply the division lemma to get
9 = 1 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 615 and 394 is 1
Notice that 1 = HCF(9,1) = HCF(10,9) = HCF(19,10) = HCF(29,19) = HCF(48,29) = HCF(173,48) = HCF(221,173) = HCF(394,221) = HCF(615,394) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 512 > 1, we apply the division lemma to 512 and 1, to get
512 = 1 x 512 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 512 is 1
Notice that 1 = HCF(512,1) .
