HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 725, 930, 205 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 725, 930, 205 is 5 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 725, 930, 205 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 725, 930, 205 is 5.
HCF(725, 930, 205) = 5
HCF of 725, 930, 205 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 725, 930, 205 is 5.
Highest Common Factor of 725,930,205 is 5
Step 1: Since 930 > 725, we apply the division lemma to 930 and 725, to get
930 = 725 x 1 + 205
Step 2: Since the reminder 725 ≠ 0, we apply division lemma to 205 and 725, to get
725 = 205 x 3 + 110
Step 3: We consider the new divisor 205 and the new remainder 110, and apply the division lemma to get
205 = 110 x 1 + 95
We consider the new divisor 110 and the new remainder 95,and apply the division lemma to get
110 = 95 x 1 + 15
We consider the new divisor 95 and the new remainder 15,and apply the division lemma to get
95 = 15 x 6 + 5
We consider the new divisor 15 and the new remainder 5,and apply the division lemma to get
15 = 5 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 725 and 930 is 5
Notice that 5 = HCF(15,5) = HCF(95,15) = HCF(110,95) = HCF(205,110) = HCF(725,205) = HCF(930,725) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 205 > 5, we apply the division lemma to 205 and 5, to get
205 = 5 x 41 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 5 and 205 is 5
Notice that 5 = HCF(205,5) .
