HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 768, 817, 754 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 768, 817, 754 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 768, 817, 754 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 768, 817, 754 is 1.
HCF(768, 817, 754) = 1
HCF of 768, 817, 754 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 768, 817, 754 is 1.
Highest Common Factor of 768,817,754 is 1
Step 1: Since 817 > 768, we apply the division lemma to 817 and 768, to get
817 = 768 x 1 + 49
Step 2: Since the reminder 768 ≠ 0, we apply division lemma to 49 and 768, to get
768 = 49 x 15 + 33
Step 3: We consider the new divisor 49 and the new remainder 33, and apply the division lemma to get
49 = 33 x 1 + 16
We consider the new divisor 33 and the new remainder 16,and apply the division lemma to get
33 = 16 x 2 + 1
We consider the new divisor 16 and the new remainder 1,and apply the division lemma to get
16 = 1 x 16 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 768 and 817 is 1
Notice that 1 = HCF(16,1) = HCF(33,16) = HCF(49,33) = HCF(768,49) = HCF(817,768) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 754 > 1, we apply the division lemma to 754 and 1, to get
754 = 1 x 754 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 754 is 1
Notice that 1 = HCF(754,1) .
