HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 509, 419, 389, 724 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 509, 419, 389, 724 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 509, 419, 389, 724 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 509, 419, 389, 724 is 1.
HCF(509, 419, 389, 724) = 1
HCF of 509, 419, 389, 724 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 509, 419, 389, 724 is 1.
Highest Common Factor of 509,419,389,724 is 1
Step 1: Since 509 > 419, we apply the division lemma to 509 and 419, to get
509 = 419 x 1 + 90
Step 2: Since the reminder 419 ≠ 0, we apply division lemma to 90 and 419, to get
419 = 90 x 4 + 59
Step 3: We consider the new divisor 90 and the new remainder 59, and apply the division lemma to get
90 = 59 x 1 + 31
We consider the new divisor 59 and the new remainder 31,and apply the division lemma to get
59 = 31 x 1 + 28
We consider the new divisor 31 and the new remainder 28,and apply the division lemma to get
31 = 28 x 1 + 3
We consider the new divisor 28 and the new remainder 3,and apply the division lemma to get
28 = 3 x 9 + 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 509 and 419 is 1
Notice that 1 = HCF(3,1) = HCF(28,3) = HCF(31,28) = HCF(59,31) = HCF(90,59) = HCF(419,90) = HCF(509,419) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 389 > 1, we apply the division lemma to 389 and 1, to get
389 = 1 x 389 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 389 is 1
Notice that 1 = HCF(389,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 724 > 1, we apply the division lemma to 724 and 1, to get
724 = 1 x 724 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 724 is 1
Notice that 1 = HCF(724,1) .
