HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 641, 387, 341 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 641, 387, 341 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 641, 387, 341 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 641, 387, 341 is 1.
HCF(641, 387, 341) = 1
HCF of 641, 387, 341 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 641, 387, 341 is 1.
Highest Common Factor of 641,387,341 is 1
Step 1: Since 641 > 387, we apply the division lemma to 641 and 387, to get
641 = 387 x 1 + 254
Step 2: Since the reminder 387 ≠ 0, we apply division lemma to 254 and 387, to get
387 = 254 x 1 + 133
Step 3: We consider the new divisor 254 and the new remainder 133, and apply the division lemma to get
254 = 133 x 1 + 121
We consider the new divisor 133 and the new remainder 121,and apply the division lemma to get
133 = 121 x 1 + 12
We consider the new divisor 121 and the new remainder 12,and apply the division lemma to get
121 = 12 x 10 + 1
We consider the new divisor 12 and the new remainder 1,and apply the division lemma to get
12 = 1 x 12 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 641 and 387 is 1
Notice that 1 = HCF(12,1) = HCF(121,12) = HCF(133,121) = HCF(254,133) = HCF(387,254) = HCF(641,387) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 341 > 1, we apply the division lemma to 341 and 1, to get
341 = 1 x 341 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 341 is 1
Notice that 1 = HCF(341,1) .
