HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 784, 476 i.e. 28 the largest integer that leaves a remainder zero for all numbers.
HCF of 784, 476 is 28 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 784, 476 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 784, 476 is 28.
HCF(784, 476) = 28
HCF of 784, 476 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 784, 476 is 28.
Highest Common Factor of 784,476 is 28
Step 1: Since 784 > 476, we apply the division lemma to 784 and 476, to get
784 = 476 x 1 + 308
Step 2: Since the reminder 476 ≠ 0, we apply division lemma to 308 and 476, to get
476 = 308 x 1 + 168
Step 3: We consider the new divisor 308 and the new remainder 168, and apply the division lemma to get
308 = 168 x 1 + 140
We consider the new divisor 168 and the new remainder 140,and apply the division lemma to get
168 = 140 x 1 + 28
We consider the new divisor 140 and the new remainder 28,and apply the division lemma to get
140 = 28 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 28, the HCF of 784 and 476 is 28
Notice that 28 = HCF(140,28) = HCF(168,140) = HCF(308,168) = HCF(476,308) = HCF(784,476) .
