HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 155, 583, 457 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 155, 583, 457 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 155, 583, 457 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 155, 583, 457 is 1.
HCF(155, 583, 457) = 1
HCF of 155, 583, 457 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 155, 583, 457 is 1.
Highest Common Factor of 155,583,457 is 1
Step 1: Since 583 > 155, we apply the division lemma to 583 and 155, to get
583 = 155 x 3 + 118
Step 2: Since the reminder 155 ≠ 0, we apply division lemma to 118 and 155, to get
155 = 118 x 1 + 37
Step 3: We consider the new divisor 118 and the new remainder 37, and apply the division lemma to get
118 = 37 x 3 + 7
We consider the new divisor 37 and the new remainder 7,and apply the division lemma to get
37 = 7 x 5 + 2
We consider the new divisor 7 and the new remainder 2,and apply the division lemma to get
7 = 2 x 3 + 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 155 and 583 is 1
Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(37,7) = HCF(118,37) = HCF(155,118) = HCF(583,155) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 457 > 1, we apply the division lemma to 457 and 1, to get
457 = 1 x 457 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 457 is 1
Notice that 1 = HCF(457,1) .
