HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 345, 485, 676, 86 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 345, 485, 676, 86 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 345, 485, 676, 86 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 345, 485, 676, 86 is 1.
HCF(345, 485, 676, 86) = 1
HCF of 345, 485, 676, 86 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 345, 485, 676, 86 is 1.
Highest Common Factor of 345,485,676,86 is 1
Step 1: Since 485 > 345, we apply the division lemma to 485 and 345, to get
485 = 345 x 1 + 140
Step 2: Since the reminder 345 ≠ 0, we apply division lemma to 140 and 345, to get
345 = 140 x 2 + 65
Step 3: We consider the new divisor 140 and the new remainder 65, and apply the division lemma to get
140 = 65 x 2 + 10
We consider the new divisor 65 and the new remainder 10,and apply the division lemma to get
65 = 10 x 6 + 5
We consider the new divisor 10 and the new remainder 5,and apply the division lemma to get
10 = 5 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 345 and 485 is 5
Notice that 5 = HCF(10,5) = HCF(65,10) = HCF(140,65) = HCF(345,140) = HCF(485,345) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 676 > 5, we apply the division lemma to 676 and 5, to get
676 = 5 x 135 + 1
Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 1 and 5, 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 5 and 676 is 1
Notice that 1 = HCF(5,1) = HCF(676,5) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 86 > 1, we apply the division lemma to 86 and 1, to get
86 = 1 x 86 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 86 is 1
Notice that 1 = HCF(86,1) .
