HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 754, 391, 681 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 754, 391, 681 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 754, 391, 681 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 754, 391, 681 is 1.
HCF(754, 391, 681) = 1
HCF of 754, 391, 681 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 754, 391, 681 is 1.
Highest Common Factor of 754,391,681 is 1
Step 1: Since 754 > 391, we apply the division lemma to 754 and 391, to get
754 = 391 x 1 + 363
Step 2: Since the reminder 391 ≠ 0, we apply division lemma to 363 and 391, to get
391 = 363 x 1 + 28
Step 3: We consider the new divisor 363 and the new remainder 28, and apply the division lemma to get
363 = 28 x 12 + 27
We consider the new divisor 28 and the new remainder 27,and apply the division lemma to get
28 = 27 x 1 + 1
We consider the new divisor 27 and the new remainder 1,and apply the division lemma to get
27 = 1 x 27 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 754 and 391 is 1
Notice that 1 = HCF(27,1) = HCF(28,27) = HCF(363,28) = HCF(391,363) = HCF(754,391) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 681 > 1, we apply the division lemma to 681 and 1, to get
681 = 1 x 681 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 681 is 1
Notice that 1 = HCF(681,1) .
