HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 162, 903, 406 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 162, 903, 406 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 162, 903, 406 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 162, 903, 406 is 1.
HCF(162, 903, 406) = 1
HCF of 162, 903, 406 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 162, 903, 406 is 1.
Highest Common Factor of 162,903,406 is 1
Step 1: Since 903 > 162, we apply the division lemma to 903 and 162, to get
903 = 162 x 5 + 93
Step 2: Since the reminder 162 ≠ 0, we apply division lemma to 93 and 162, to get
162 = 93 x 1 + 69
Step 3: We consider the new divisor 93 and the new remainder 69, and apply the division lemma to get
93 = 69 x 1 + 24
We consider the new divisor 69 and the new remainder 24,and apply the division lemma to get
69 = 24 x 2 + 21
We consider the new divisor 24 and the new remainder 21,and apply the division lemma to get
24 = 21 x 1 + 3
We consider the new divisor 21 and the new remainder 3,and apply the division lemma to get
21 = 3 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 162 and 903 is 3
Notice that 3 = HCF(21,3) = HCF(24,21) = HCF(69,24) = HCF(93,69) = HCF(162,93) = HCF(903,162) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 406 > 3, we apply the division lemma to 406 and 3, to get
406 = 3 x 135 + 1
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, 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 3 and 406 is 1
Notice that 1 = HCF(3,1) = HCF(406,3) .
