HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 965, 755, 557, 10 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 965, 755, 557, 10 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 965, 755, 557, 10 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 965, 755, 557, 10 is 1.
HCF(965, 755, 557, 10) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 965, 755, 557, 10 is 1.
Step 1: Since 965 > 755, we apply the division lemma to 965 and 755, to get
965 = 755 x 1 + 210
Step 2: Since the reminder 755 ≠ 0, we apply division lemma to 210 and 755, to get
755 = 210 x 3 + 125
Step 3: We consider the new divisor 210 and the new remainder 125, and apply the division lemma to get
210 = 125 x 1 + 85
We consider the new divisor 125 and the new remainder 85,and apply the division lemma to get
125 = 85 x 1 + 40
We consider the new divisor 85 and the new remainder 40,and apply the division lemma to get
85 = 40 x 2 + 5
We consider the new divisor 40 and the new remainder 5,and apply the division lemma to get
40 = 5 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 965 and 755 is 5
Notice that 5 = HCF(40,5) = HCF(85,40) = HCF(125,85) = HCF(210,125) = HCF(755,210) = HCF(965,755) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 557 > 5, we apply the division lemma to 557 and 5, to get
557 = 5 x 111 + 2
Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 2 and 5, to get
5 = 2 x 2 + 1
Step 3: We consider the new divisor 2 and the new remainder 1, and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 5 and 557 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(557,5) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 10 > 1, we apply the division lemma to 10 and 1, to get
10 = 1 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 10 is 1
Notice that 1 = HCF(10,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
