HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 915, 571, 150, 728 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 915, 571, 150, 728 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 915, 571, 150, 728 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 915, 571, 150, 728 is 1.
HCF(915, 571, 150, 728) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 915, 571, 150, 728 is 1.
Step 1: Since 915 > 571, we apply the division lemma to 915 and 571, to get
915 = 571 x 1 + 344
Step 2: Since the reminder 571 ≠ 0, we apply division lemma to 344 and 571, to get
571 = 344 x 1 + 227
Step 3: We consider the new divisor 344 and the new remainder 227, and apply the division lemma to get
344 = 227 x 1 + 117
We consider the new divisor 227 and the new remainder 117,and apply the division lemma to get
227 = 117 x 1 + 110
We consider the new divisor 117 and the new remainder 110,and apply the division lemma to get
117 = 110 x 1 + 7
We consider the new divisor 110 and the new remainder 7,and apply the division lemma to get
110 = 7 x 15 + 5
We consider the new divisor 7 and the new remainder 5,and apply the division lemma to get
7 = 5 x 1 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 1
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 915 and 571 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(7,5) = HCF(110,7) = HCF(117,110) = HCF(227,117) = HCF(344,227) = HCF(571,344) = HCF(915,571) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 150 > 1, we apply the division lemma to 150 and 1, to get
150 = 1 x 150 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 150 is 1
Notice that 1 = HCF(150,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 728 > 1, we apply the division lemma to 728 and 1, to get
728 = 1 x 728 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 728 is 1
Notice that 1 = HCF(728,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
