HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 371, 225, 157, 349 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 371, 225, 157, 349 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 371, 225, 157, 349 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 371, 225, 157, 349 is 1.
HCF(371, 225, 157, 349) = 1
HCF of 371, 225, 157, 349 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 371, 225, 157, 349 is 1.
Highest Common Factor of 371,225,157,349 is 1
Step 1: Since 371 > 225, we apply the division lemma to 371 and 225, to get
371 = 225 x 1 + 146
Step 2: Since the reminder 225 ≠ 0, we apply division lemma to 146 and 225, to get
225 = 146 x 1 + 79
Step 3: We consider the new divisor 146 and the new remainder 79, and apply the division lemma to get
146 = 79 x 1 + 67
We consider the new divisor 79 and the new remainder 67,and apply the division lemma to get
79 = 67 x 1 + 12
We consider the new divisor 67 and the new remainder 12,and apply the division lemma to get
67 = 12 x 5 + 7
We consider the new divisor 12 and the new remainder 7,and apply the division lemma to get
12 = 7 x 1 + 5
We consider the new divisor 7 and the new remainder 5,and apply the division lemma to get
7 = 5 x 1 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 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 371 and 225 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(7,5) = HCF(12,7) = HCF(67,12) = HCF(79,67) = HCF(146,79) = HCF(225,146) = HCF(371,225) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 157 > 1, we apply the division lemma to 157 and 1, to get
157 = 1 x 157 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 157 is 1
Notice that 1 = HCF(157,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 349 > 1, we apply the division lemma to 349 and 1, to get
349 = 1 x 349 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 349 is 1
Notice that 1 = HCF(349,1) .
