HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 453, 155 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 453, 155 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 453, 155 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 453, 155 is 1.
HCF(453, 155) = 1
HCF of 453, 155 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 453, 155 is 1.
Highest Common Factor of 453,155 is 1
Step 1: Since 453 > 155, we apply the division lemma to 453 and 155, to get
453 = 155 x 2 + 143
Step 2: Since the reminder 155 ≠ 0, we apply division lemma to 143 and 155, to get
155 = 143 x 1 + 12
Step 3: We consider the new divisor 143 and the new remainder 12, and apply the division lemma to get
143 = 12 x 11 + 11
We consider the new divisor 12 and the new remainder 11,and apply the division lemma to get
12 = 11 x 1 + 1
We consider the new divisor 11 and the new remainder 1,and apply the division lemma to get
11 = 1 x 11 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 453 and 155 is 1
Notice that 1 = HCF(11,1) = HCF(12,11) = HCF(143,12) = HCF(155,143) = HCF(453,155) .
