HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 472, 800, 540 i.e. 4 the largest integer that leaves a remainder zero for all numbers.
HCF of 472, 800, 540 is 4 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 472, 800, 540 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 472, 800, 540 is 4.
HCF(472, 800, 540) = 4
HCF of 472, 800, 540 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 472, 800, 540 is 4.
Highest Common Factor of 472,800,540 is 4
Step 1: Since 800 > 472, we apply the division lemma to 800 and 472, to get
800 = 472 x 1 + 328
Step 2: Since the reminder 472 ≠ 0, we apply division lemma to 328 and 472, to get
472 = 328 x 1 + 144
Step 3: We consider the new divisor 328 and the new remainder 144, and apply the division lemma to get
328 = 144 x 2 + 40
We consider the new divisor 144 and the new remainder 40,and apply the division lemma to get
144 = 40 x 3 + 24
We consider the new divisor 40 and the new remainder 24,and apply the division lemma to get
40 = 24 x 1 + 16
We consider the new divisor 24 and the new remainder 16,and apply the division lemma to get
24 = 16 x 1 + 8
We consider the new divisor 16 and the new remainder 8,and apply the division lemma to get
16 = 8 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 8, the HCF of 472 and 800 is 8
Notice that 8 = HCF(16,8) = HCF(24,16) = HCF(40,24) = HCF(144,40) = HCF(328,144) = HCF(472,328) = HCF(800,472) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 540 > 8, we apply the division lemma to 540 and 8, to get
540 = 8 x 67 + 4
Step 2: Since the reminder 8 ≠ 0, we apply division lemma to 4 and 8, to get
8 = 4 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 8 and 540 is 4
Notice that 4 = HCF(8,4) = HCF(540,8) .
