HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 159, 4122, 7378 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 159, 4122, 7378 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 159, 4122, 7378 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 159, 4122, 7378 is 1.
HCF(159, 4122, 7378) = 1
HCF of 159, 4122, 7378 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 159, 4122, 7378 is 1.
Highest Common Factor of 159,4122,7378 is 1
Step 1: Since 4122 > 159, we apply the division lemma to 4122 and 159, to get
4122 = 159 x 25 + 147
Step 2: Since the reminder 159 ≠ 0, we apply division lemma to 147 and 159, to get
159 = 147 x 1 + 12
Step 3: We consider the new divisor 147 and the new remainder 12, and apply the division lemma to get
147 = 12 x 12 + 3
We consider the new divisor 12 and the new remainder 3, and apply the division lemma to get
12 = 3 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 159 and 4122 is 3
Notice that 3 = HCF(12,3) = HCF(147,12) = HCF(159,147) = HCF(4122,159) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 7378 > 3, we apply the division lemma to 7378 and 3, to get
7378 = 3 x 2459 + 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 7378 is 1
Notice that 1 = HCF(3,1) = HCF(7378,3) .
