HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 779, 307, 545, 48 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 779, 307, 545, 48 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 779, 307, 545, 48 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 779, 307, 545, 48 is 1.
HCF(779, 307, 545, 48) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 779, 307, 545, 48 is 1.
Step 1: Since 779 > 307, we apply the division lemma to 779 and 307, to get
779 = 307 x 2 + 165
Step 2: Since the reminder 307 ≠ 0, we apply division lemma to 165 and 307, to get
307 = 165 x 1 + 142
Step 3: We consider the new divisor 165 and the new remainder 142, and apply the division lemma to get
165 = 142 x 1 + 23
We consider the new divisor 142 and the new remainder 23,and apply the division lemma to get
142 = 23 x 6 + 4
We consider the new divisor 23 and the new remainder 4,and apply the division lemma to get
23 = 4 x 5 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 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 779 and 307 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(23,4) = HCF(142,23) = HCF(165,142) = HCF(307,165) = HCF(779,307) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 545 > 1, we apply the division lemma to 545 and 1, to get
545 = 1 x 545 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 545 is 1
Notice that 1 = HCF(545,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 48 > 1, we apply the division lemma to 48 and 1, to get
48 = 1 x 48 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 48 is 1
Notice that 1 = HCF(48,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
