HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 165, 818, 738 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 165, 818, 738 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 165, 818, 738 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 165, 818, 738 is 1.
HCF(165, 818, 738) = 1
HCF of 165, 818, 738 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 165, 818, 738 is 1.
Highest Common Factor of 165,818,738 is 1
Step 1: Since 818 > 165, we apply the division lemma to 818 and 165, to get
818 = 165 x 4 + 158
Step 2: Since the reminder 165 ≠ 0, we apply division lemma to 158 and 165, to get
165 = 158 x 1 + 7
Step 3: We consider the new divisor 158 and the new remainder 7, and apply the division lemma to get
158 = 7 x 22 + 4
We consider the new divisor 7 and the new remainder 4,and apply the division lemma to get
7 = 4 x 1 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 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 165 and 818 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(158,7) = HCF(165,158) = HCF(818,165) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 738 > 1, we apply the division lemma to 738 and 1, to get
738 = 1 x 738 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 738 is 1
Notice that 1 = HCF(738,1) .
