HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 191, 370, 351 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 191, 370, 351 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 191, 370, 351 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 191, 370, 351 is 1.
HCF(191, 370, 351) = 1
HCF of 191, 370, 351 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 191, 370, 351 is 1.
Highest Common Factor of 191,370,351 is 1
Step 1: Since 370 > 191, we apply the division lemma to 370 and 191, to get
370 = 191 x 1 + 179
Step 2: Since the reminder 191 ≠ 0, we apply division lemma to 179 and 191, to get
191 = 179 x 1 + 12
Step 3: We consider the new divisor 179 and the new remainder 12, and apply the division lemma to get
179 = 12 x 14 + 11
We consider the new divisor 12 and the new remainder 11,and apply the division lemma to get
12 = 11 x 1 + 1
We consider the new divisor 11 and the new remainder 1,and apply the division lemma to get
11 = 1 x 11 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 191 and 370 is 1
Notice that 1 = HCF(11,1) = HCF(12,11) = HCF(179,12) = HCF(191,179) = HCF(370,191) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 351 > 1, we apply the division lemma to 351 and 1, to get
351 = 1 x 351 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 351 is 1
Notice that 1 = HCF(351,1) .
