HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 1497, 6439, 73651 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 1497, 6439, 73651 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 1497, 6439, 73651 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 1497, 6439, 73651 is 1.
HCF(1497, 6439, 73651) = 1
HCF of 1497, 6439, 73651 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 1497, 6439, 73651 is 1.
Highest Common Factor of 1497,6439,73651 is 1
Step 1: Since 6439 > 1497, we apply the division lemma to 6439 and 1497, to get
6439 = 1497 x 4 + 451
Step 2: Since the reminder 1497 ≠ 0, we apply division lemma to 451 and 1497, to get
1497 = 451 x 3 + 144
Step 3: We consider the new divisor 451 and the new remainder 144, and apply the division lemma to get
451 = 144 x 3 + 19
We consider the new divisor 144 and the new remainder 19,and apply the division lemma to get
144 = 19 x 7 + 11
We consider the new divisor 19 and the new remainder 11,and apply the division lemma to get
19 = 11 x 1 + 8
We consider the new divisor 11 and the new remainder 8,and apply the division lemma to get
11 = 8 x 1 + 3
We consider the new divisor 8 and the new remainder 3,and apply the division lemma to get
8 = 3 x 2 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 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 1497 and 6439 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(8,3) = HCF(11,8) = HCF(19,11) = HCF(144,19) = HCF(451,144) = HCF(1497,451) = HCF(6439,1497) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 73651 > 1, we apply the division lemma to 73651 and 1, to get
73651 = 1 x 73651 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 73651 is 1
Notice that 1 = HCF(73651,1) .
