HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 655, 514, 485 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 655, 514, 485 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 655, 514, 485 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 655, 514, 485 is 1.
HCF(655, 514, 485) = 1
HCF of 655, 514, 485 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 655, 514, 485 is 1.
Highest Common Factor of 655,514,485 is 1
Step 1: Since 655 > 514, we apply the division lemma to 655 and 514, to get
655 = 514 x 1 + 141
Step 2: Since the reminder 514 ≠ 0, we apply division lemma to 141 and 514, to get
514 = 141 x 3 + 91
Step 3: We consider the new divisor 141 and the new remainder 91, and apply the division lemma to get
141 = 91 x 1 + 50
We consider the new divisor 91 and the new remainder 50,and apply the division lemma to get
91 = 50 x 1 + 41
We consider the new divisor 50 and the new remainder 41,and apply the division lemma to get
50 = 41 x 1 + 9
We consider the new divisor 41 and the new remainder 9,and apply the division lemma to get
41 = 9 x 4 + 5
We consider the new divisor 9 and the new remainder 5,and apply the division lemma to get
9 = 5 x 1 + 4
We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get
5 = 4 x 1 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 655 and 514 is 1
Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(9,5) = HCF(41,9) = HCF(50,41) = HCF(91,50) = HCF(141,91) = HCF(514,141) = HCF(655,514) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 485 > 1, we apply the division lemma to 485 and 1, to get
485 = 1 x 485 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 485 is 1
Notice that 1 = HCF(485,1) .
