HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 717, 980, 479, 764 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 717, 980, 479, 764 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 717, 980, 479, 764 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 717, 980, 479, 764 is 1.
HCF(717, 980, 479, 764) = 1
HCF of 717, 980, 479, 764 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 717, 980, 479, 764 is 1.
Highest Common Factor of 717,980,479,764 is 1
Step 1: Since 980 > 717, we apply the division lemma to 980 and 717, to get
980 = 717 x 1 + 263
Step 2: Since the reminder 717 ≠ 0, we apply division lemma to 263 and 717, to get
717 = 263 x 2 + 191
Step 3: We consider the new divisor 263 and the new remainder 191, and apply the division lemma to get
263 = 191 x 1 + 72
We consider the new divisor 191 and the new remainder 72,and apply the division lemma to get
191 = 72 x 2 + 47
We consider the new divisor 72 and the new remainder 47,and apply the division lemma to get
72 = 47 x 1 + 25
We consider the new divisor 47 and the new remainder 25,and apply the division lemma to get
47 = 25 x 1 + 22
We consider the new divisor 25 and the new remainder 22,and apply the division lemma to get
25 = 22 x 1 + 3
We consider the new divisor 22 and the new remainder 3,and apply the division lemma to get
22 = 3 x 7 + 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 717 and 980 is 1
Notice that 1 = HCF(3,1) = HCF(22,3) = HCF(25,22) = HCF(47,25) = HCF(72,47) = HCF(191,72) = HCF(263,191) = HCF(717,263) = HCF(980,717) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 479 > 1, we apply the division lemma to 479 and 1, to get
479 = 1 x 479 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 479 is 1
Notice that 1 = HCF(479,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 764 > 1, we apply the division lemma to 764 and 1, to get
764 = 1 x 764 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 764 is 1
Notice that 1 = HCF(764,1) .
