HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 495, 25919 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 495, 25919 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 495, 25919 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 495, 25919 is 1.
HCF(495, 25919) = 1
HCF of 495, 25919 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 495, 25919 is 1.
Highest Common Factor of 495,25919 is 1
Step 1: Since 25919 > 495, we apply the division lemma to 25919 and 495, to get
25919 = 495 x 52 + 179
Step 2: Since the reminder 495 ≠ 0, we apply division lemma to 179 and 495, to get
495 = 179 x 2 + 137
Step 3: We consider the new divisor 179 and the new remainder 137, and apply the division lemma to get
179 = 137 x 1 + 42
We consider the new divisor 137 and the new remainder 42,and apply the division lemma to get
137 = 42 x 3 + 11
We consider the new divisor 42 and the new remainder 11,and apply the division lemma to get
42 = 11 x 3 + 9
We consider the new divisor 11 and the new remainder 9,and apply the division lemma to get
11 = 9 x 1 + 2
We consider the new divisor 9 and the new remainder 2,and apply the division lemma to get
9 = 2 x 4 + 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 495 and 25919 is 1
Notice that 1 = HCF(2,1) = HCF(9,2) = HCF(11,9) = HCF(42,11) = HCF(137,42) = HCF(179,137) = HCF(495,179) = HCF(25919,495) .
