HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 144, 320, 471 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 144, 320, 471 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 144, 320, 471 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 144, 320, 471 is 1.
HCF(144, 320, 471) = 1
HCF of 144, 320, 471 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 144, 320, 471 is 1.
Highest Common Factor of 144,320,471 is 1
Step 1: Since 320 > 144, we apply the division lemma to 320 and 144, to get
320 = 144 x 2 + 32
Step 2: Since the reminder 144 ≠ 0, we apply division lemma to 32 and 144, to get
144 = 32 x 4 + 16
Step 3: We consider the new divisor 32 and the new remainder 16, and apply the division lemma to get
32 = 16 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 16, the HCF of 144 and 320 is 16
Notice that 16 = HCF(32,16) = HCF(144,32) = HCF(320,144) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 471 > 16, we apply the division lemma to 471 and 16, to get
471 = 16 x 29 + 7
Step 2: Since the reminder 16 ≠ 0, we apply division lemma to 7 and 16, to get
16 = 7 x 2 + 2
Step 3: We consider the new divisor 7 and the new remainder 2, and apply the division lemma to get
7 = 2 x 3 + 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 16 and 471 is 1
Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(16,7) = HCF(471,16) .
