HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 579, 780, 417 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 579, 780, 417 is 3 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 579, 780, 417 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 579, 780, 417 is 3.
HCF(579, 780, 417) = 3
HCF of 579, 780, 417 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 579, 780, 417 is 3.
Highest Common Factor of 579,780,417 is 3
Step 1: Since 780 > 579, we apply the division lemma to 780 and 579, to get
780 = 579 x 1 + 201
Step 2: Since the reminder 579 ≠ 0, we apply division lemma to 201 and 579, to get
579 = 201 x 2 + 177
Step 3: We consider the new divisor 201 and the new remainder 177, and apply the division lemma to get
201 = 177 x 1 + 24
We consider the new divisor 177 and the new remainder 24,and apply the division lemma to get
177 = 24 x 7 + 9
We consider the new divisor 24 and the new remainder 9,and apply the division lemma to get
24 = 9 x 2 + 6
We consider the new divisor 9 and the new remainder 6,and apply the division lemma to get
9 = 6 x 1 + 3
We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 579 and 780 is 3
Notice that 3 = HCF(6,3) = HCF(9,6) = HCF(24,9) = HCF(177,24) = HCF(201,177) = HCF(579,201) = HCF(780,579) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 417 > 3, we apply the division lemma to 417 and 3, to get
417 = 3 x 139 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 417 is 3
Notice that 3 = HCF(417,3) .
