HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 342, 150, 817 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 342, 150, 817 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 342, 150, 817 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 342, 150, 817 is 1.
HCF(342, 150, 817) = 1
HCF of 342, 150, 817 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 342, 150, 817 is 1.
Highest Common Factor of 342,150,817 is 1
Step 1: Since 342 > 150, we apply the division lemma to 342 and 150, to get
342 = 150 x 2 + 42
Step 2: Since the reminder 150 ≠ 0, we apply division lemma to 42 and 150, to get
150 = 42 x 3 + 24
Step 3: We consider the new divisor 42 and the new remainder 24, and apply the division lemma to get
42 = 24 x 1 + 18
We consider the new divisor 24 and the new remainder 18,and apply the division lemma to get
24 = 18 x 1 + 6
We consider the new divisor 18 and the new remainder 6,and apply the division lemma to get
18 = 6 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 342 and 150 is 6
Notice that 6 = HCF(18,6) = HCF(24,18) = HCF(42,24) = HCF(150,42) = HCF(342,150) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 817 > 6, we apply the division lemma to 817 and 6, to get
817 = 6 x 136 + 1
Step 2: Since the reminder 6 ≠ 0, we apply division lemma to 1 and 6, to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 6 and 817 is 1
Notice that 1 = HCF(6,1) = HCF(817,6) .
