HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 915, 305, 425 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 915, 305, 425 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 915, 305, 425 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, 305, 425 is 5.
HCF(915, 305, 425) = 5
HCF of 915, 305, 425 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 915, 305, 425 is 5.
Highest Common Factor of 915,305,425 is 5
Step 1: Since 915 > 305, we apply the division lemma to 915 and 305, to get
915 = 305 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 305, the HCF of 915 and 305 is 305
Notice that 305 = HCF(915,305) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 425 > 305, we apply the division lemma to 425 and 305, to get
425 = 305 x 1 + 120
Step 2: Since the reminder 305 ≠ 0, we apply division lemma to 120 and 305, to get
305 = 120 x 2 + 65
Step 3: We consider the new divisor 120 and the new remainder 65, and apply the division lemma to get
120 = 65 x 1 + 55
We consider the new divisor 65 and the new remainder 55,and apply the division lemma to get
65 = 55 x 1 + 10
We consider the new divisor 55 and the new remainder 10,and apply the division lemma to get
55 = 10 x 5 + 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 305 and 425 is 5
Notice that 5 = HCF(10,5) = HCF(55,10) = HCF(65,55) = HCF(120,65) = HCF(305,120) = HCF(425,305) .
