HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 556, 784 i.e. 4 the largest integer that leaves a remainder zero for all numbers.
HCF of 556, 784 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 556, 784 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 556, 784 is 4.
HCF(556, 784) = 4
HCF of 556, 784 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 556, 784 is 4.
Highest Common Factor of 556,784 is 4
Step 1: Since 784 > 556, we apply the division lemma to 784 and 556, to get
784 = 556 x 1 + 228
Step 2: Since the reminder 556 ≠ 0, we apply division lemma to 228 and 556, to get
556 = 228 x 2 + 100
Step 3: We consider the new divisor 228 and the new remainder 100, and apply the division lemma to get
228 = 100 x 2 + 28
We consider the new divisor 100 and the new remainder 28,and apply the division lemma to get
100 = 28 x 3 + 16
We consider the new divisor 28 and the new remainder 16,and apply the division lemma to get
28 = 16 x 1 + 12
We consider the new divisor 16 and the new remainder 12,and apply the division lemma to get
16 = 12 x 1 + 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 556 and 784 is 4
Notice that 4 = HCF(12,4) = HCF(16,12) = HCF(28,16) = HCF(100,28) = HCF(228,100) = HCF(556,228) = HCF(784,556) .
