HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 472, 784, 408 i.e. 8 the largest integer that leaves a remainder zero for all numbers.
HCF of 472, 784, 408 is 8 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, 784, 408 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, 784, 408 is 8.
HCF(472, 784, 408) = 8
HCF of 472, 784, 408 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, 784, 408 is 8.
Highest Common Factor of 472,784,408 is 8
Step 1: Since 784 > 472, we apply the division lemma to 784 and 472, to get
784 = 472 x 1 + 312
Step 2: Since the reminder 472 ≠ 0, we apply division lemma to 312 and 472, to get
472 = 312 x 1 + 160
Step 3: We consider the new divisor 312 and the new remainder 160, and apply the division lemma to get
312 = 160 x 1 + 152
We consider the new divisor 160 and the new remainder 152,and apply the division lemma to get
160 = 152 x 1 + 8
We consider the new divisor 152 and the new remainder 8,and apply the division lemma to get
152 = 8 x 19 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 8, the HCF of 472 and 784 is 8
Notice that 8 = HCF(152,8) = HCF(160,152) = HCF(312,160) = HCF(472,312) = HCF(784,472) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 408 > 8, we apply the division lemma to 408 and 8, to get
408 = 8 x 51 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 8, the HCF of 8 and 408 is 8
Notice that 8 = HCF(408,8) .
