HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 395, 916, 545 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 395, 916, 545 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 395, 916, 545 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 395, 916, 545 is 1.
HCF(395, 916, 545) = 1
HCF of 395, 916, 545 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 395, 916, 545 is 1.
Highest Common Factor of 395,916,545 is 1
Step 1: Since 916 > 395, we apply the division lemma to 916 and 395, to get
916 = 395 x 2 + 126
Step 2: Since the reminder 395 ≠ 0, we apply division lemma to 126 and 395, to get
395 = 126 x 3 + 17
Step 3: We consider the new divisor 126 and the new remainder 17, and apply the division lemma to get
126 = 17 x 7 + 7
We consider the new divisor 17 and the new remainder 7,and apply the division lemma to get
17 = 7 x 2 + 3
We consider the new divisor 7 and the new remainder 3,and apply the division lemma to get
7 = 3 x 2 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 395 and 916 is 1
Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(17,7) = HCF(126,17) = HCF(395,126) = HCF(916,395) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 545 > 1, we apply the division lemma to 545 and 1, to get
545 = 1 x 545 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 545 is 1
Notice that 1 = HCF(545,1) .
