HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 945, 415 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 945, 415 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 945, 415 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 945, 415 is 5.
HCF(945, 415) = 5
HCF of 945, 415 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 945, 415 is 5.
Highest Common Factor of 945,415 is 5
Step 1: Since 945 > 415, we apply the division lemma to 945 and 415, to get
945 = 415 x 2 + 115
Step 2: Since the reminder 415 ≠ 0, we apply division lemma to 115 and 415, to get
415 = 115 x 3 + 70
Step 3: We consider the new divisor 115 and the new remainder 70, and apply the division lemma to get
115 = 70 x 1 + 45
We consider the new divisor 70 and the new remainder 45,and apply the division lemma to get
70 = 45 x 1 + 25
We consider the new divisor 45 and the new remainder 25,and apply the division lemma to get
45 = 25 x 1 + 20
We consider the new divisor 25 and the new remainder 20,and apply the division lemma to get
25 = 20 x 1 + 5
We consider the new divisor 20 and the new remainder 5,and apply the division lemma to get
20 = 5 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 945 and 415 is 5
Notice that 5 = HCF(20,5) = HCF(25,20) = HCF(45,25) = HCF(70,45) = HCF(115,70) = HCF(415,115) = HCF(945,415) .
