HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 152, 285, 305 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 152, 285, 305 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 152, 285, 305 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 152, 285, 305 is 1.
HCF(152, 285, 305) = 1
HCF of 152, 285, 305 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 152, 285, 305 is 1.
Highest Common Factor of 152,285,305 is 1
Step 1: Since 285 > 152, we apply the division lemma to 285 and 152, to get
285 = 152 x 1 + 133
Step 2: Since the reminder 152 ≠ 0, we apply division lemma to 133 and 152, to get
152 = 133 x 1 + 19
Step 3: We consider the new divisor 133 and the new remainder 19, and apply the division lemma to get
133 = 19 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 19, the HCF of 152 and 285 is 19
Notice that 19 = HCF(133,19) = HCF(152,133) = HCF(285,152) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 305 > 19, we apply the division lemma to 305 and 19, to get
305 = 19 x 16 + 1
Step 2: Since the reminder 19 ≠ 0, we apply division lemma to 1 and 19, to get
19 = 1 x 19 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 19 and 305 is 1
Notice that 1 = HCF(19,1) = HCF(305,19) .
