HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 165, 885, 152 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 165, 885, 152 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 165, 885, 152 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 165, 885, 152 is 1.
HCF(165, 885, 152) = 1
HCF of 165, 885, 152 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 165, 885, 152 is 1.
Highest Common Factor of 165,885,152 is 1
Step 1: Since 885 > 165, we apply the division lemma to 885 and 165, to get
885 = 165 x 5 + 60
Step 2: Since the reminder 165 ≠ 0, we apply division lemma to 60 and 165, to get
165 = 60 x 2 + 45
Step 3: We consider the new divisor 60 and the new remainder 45, and apply the division lemma to get
60 = 45 x 1 + 15
We consider the new divisor 45 and the new remainder 15, and apply the division lemma to get
45 = 15 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 15, the HCF of 165 and 885 is 15
Notice that 15 = HCF(45,15) = HCF(60,45) = HCF(165,60) = HCF(885,165) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 152 > 15, we apply the division lemma to 152 and 15, to get
152 = 15 x 10 + 2
Step 2: Since the reminder 15 ≠ 0, we apply division lemma to 2 and 15, to get
15 = 2 x 7 + 1
Step 3: 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 15 and 152 is 1
Notice that 1 = HCF(2,1) = HCF(15,2) = HCF(152,15) .
