HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 487, 917, 759, 548 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 487, 917, 759, 548 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 487, 917, 759, 548 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 487, 917, 759, 548 is 1.
HCF(487, 917, 759, 548) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 487, 917, 759, 548 is 1.
Step 1: Since 917 > 487, we apply the division lemma to 917 and 487, to get
917 = 487 x 1 + 430
Step 2: Since the reminder 487 ≠ 0, we apply division lemma to 430 and 487, to get
487 = 430 x 1 + 57
Step 3: We consider the new divisor 430 and the new remainder 57, and apply the division lemma to get
430 = 57 x 7 + 31
We consider the new divisor 57 and the new remainder 31,and apply the division lemma to get
57 = 31 x 1 + 26
We consider the new divisor 31 and the new remainder 26,and apply the division lemma to get
31 = 26 x 1 + 5
We consider the new divisor 26 and the new remainder 5,and apply the division lemma to get
26 = 5 x 5 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 487 and 917 is 1
Notice that 1 = HCF(5,1) = HCF(26,5) = HCF(31,26) = HCF(57,31) = HCF(430,57) = HCF(487,430) = HCF(917,487) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 759 > 1, we apply the division lemma to 759 and 1, to get
759 = 1 x 759 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 759 is 1
Notice that 1 = HCF(759,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 548 > 1, we apply the division lemma to 548 and 1, to get
548 = 1 x 548 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 548 is 1
Notice that 1 = HCF(548,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
