HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 653, 405, 412 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 653, 405, 412 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 653, 405, 412 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 653, 405, 412 is 1.
HCF(653, 405, 412) = 1
HCF of 653, 405, 412 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 653, 405, 412 is 1.
Highest Common Factor of 653,405,412 is 1
Step 1: Since 653 > 405, we apply the division lemma to 653 and 405, to get
653 = 405 x 1 + 248
Step 2: Since the reminder 405 ≠ 0, we apply division lemma to 248 and 405, to get
405 = 248 x 1 + 157
Step 3: We consider the new divisor 248 and the new remainder 157, and apply the division lemma to get
248 = 157 x 1 + 91
We consider the new divisor 157 and the new remainder 91,and apply the division lemma to get
157 = 91 x 1 + 66
We consider the new divisor 91 and the new remainder 66,and apply the division lemma to get
91 = 66 x 1 + 25
We consider the new divisor 66 and the new remainder 25,and apply the division lemma to get
66 = 25 x 2 + 16
We consider the new divisor 25 and the new remainder 16,and apply the division lemma to get
25 = 16 x 1 + 9
We consider the new divisor 16 and the new remainder 9,and apply the division lemma to get
16 = 9 x 1 + 7
We consider the new divisor 9 and the new remainder 7,and apply the division lemma to get
9 = 7 x 1 + 2
We consider the new divisor 7 and the new remainder 2,and apply the division lemma to get
7 = 2 x 3 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma 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 653 and 405 is 1
Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(9,7) = HCF(16,9) = HCF(25,16) = HCF(66,25) = HCF(91,66) = HCF(157,91) = HCF(248,157) = HCF(405,248) = HCF(653,405) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 412 > 1, we apply the division lemma to 412 and 1, to get
412 = 1 x 412 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 412 is 1
Notice that 1 = HCF(412,1) .
