HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 155, 272, 499 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 155, 272, 499 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, 272, 499 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, 272, 499 is 1.
HCF(155, 272, 499) = 1
HCF of 155, 272, 499 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, 272, 499 is 1.
Highest Common Factor of 155,272,499 is 1
Step 1: Since 272 > 155, we apply the division lemma to 272 and 155, to get
272 = 155 x 1 + 117
Step 2: Since the reminder 155 ≠ 0, we apply division lemma to 117 and 155, to get
155 = 117 x 1 + 38
Step 3: We consider the new divisor 117 and the new remainder 38, and apply the division lemma to get
117 = 38 x 3 + 3
We consider the new divisor 38 and the new remainder 3,and apply the division lemma to get
38 = 3 x 12 + 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 155 and 272 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(38,3) = HCF(117,38) = HCF(155,117) = HCF(272,155) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 499 > 1, we apply the division lemma to 499 and 1, to get
499 = 1 x 499 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 499 is 1
Notice that 1 = HCF(499,1) .
