HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 472, 740, 16 i.e. 4 the largest integer that leaves a remainder zero for all numbers.
HCF of 472, 740, 16 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, 740, 16 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, 740, 16 is 4.
HCF(472, 740, 16) = 4
HCF of 472, 740, 16 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, 740, 16 is 4.
Highest Common Factor of 472,740,16 is 4
Step 1: Since 740 > 472, we apply the division lemma to 740 and 472, to get
740 = 472 x 1 + 268
Step 2: Since the reminder 472 ≠ 0, we apply division lemma to 268 and 472, to get
472 = 268 x 1 + 204
Step 3: We consider the new divisor 268 and the new remainder 204, and apply the division lemma to get
268 = 204 x 1 + 64
We consider the new divisor 204 and the new remainder 64,and apply the division lemma to get
204 = 64 x 3 + 12
We consider the new divisor 64 and the new remainder 12,and apply the division lemma to get
64 = 12 x 5 + 4
We consider the new divisor 12 and the new remainder 4,and apply the division lemma to get
12 = 4 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 472 and 740 is 4
Notice that 4 = HCF(12,4) = HCF(64,12) = HCF(204,64) = HCF(268,204) = HCF(472,268) = HCF(740,472) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 16 > 4, we apply the division lemma to 16 and 4, to get
16 = 4 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 4 and 16 is 4
Notice that 4 = HCF(16,4) .
