HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 436, 28151 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 436, 28151 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 436, 28151 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 436, 28151 is 1.
HCF(436, 28151) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 436, 28151 is 1.
Step 1: Since 28151 > 436, we apply the division lemma to 28151 and 436, to get
28151 = 436 x 64 + 247
Step 2: Since the reminder 436 ≠ 0, we apply division lemma to 247 and 436, to get
436 = 247 x 1 + 189
Step 3: We consider the new divisor 247 and the new remainder 189, and apply the division lemma to get
247 = 189 x 1 + 58
We consider the new divisor 189 and the new remainder 58,and apply the division lemma to get
189 = 58 x 3 + 15
We consider the new divisor 58 and the new remainder 15,and apply the division lemma to get
58 = 15 x 3 + 13
We consider the new divisor 15 and the new remainder 13,and apply the division lemma to get
15 = 13 x 1 + 2
We consider the new divisor 13 and the new remainder 2,and apply the division lemma to get
13 = 2 x 6 + 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 436 and 28151 is 1
Notice that 1 = HCF(2,1) = HCF(13,2) = HCF(15,13) = HCF(58,15) = HCF(189,58) = HCF(247,189) = HCF(436,247) = HCF(28151,436) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?
