HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 780, 301, 865 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 780, 301, 865 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 780, 301, 865 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 780, 301, 865 is 1.
HCF(780, 301, 865) = 1
HCF of 780, 301, 865 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 780, 301, 865 is 1.
Highest Common Factor of 780,301,865 is 1
Step 1: Since 780 > 301, we apply the division lemma to 780 and 301, to get
780 = 301 x 2 + 178
Step 2: Since the reminder 301 ≠ 0, we apply division lemma to 178 and 301, to get
301 = 178 x 1 + 123
Step 3: We consider the new divisor 178 and the new remainder 123, and apply the division lemma to get
178 = 123 x 1 + 55
We consider the new divisor 123 and the new remainder 55,and apply the division lemma to get
123 = 55 x 2 + 13
We consider the new divisor 55 and the new remainder 13,and apply the division lemma to get
55 = 13 x 4 + 3
We consider the new divisor 13 and the new remainder 3,and apply the division lemma to get
13 = 3 x 4 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 780 and 301 is 1
Notice that 1 = HCF(3,1) = HCF(13,3) = HCF(55,13) = HCF(123,55) = HCF(178,123) = HCF(301,178) = HCF(780,301) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 865 > 1, we apply the division lemma to 865 and 1, to get
865 = 1 x 865 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 865 is 1
Notice that 1 = HCF(865,1) .
