HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 556, 778 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 556, 778 is 2 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, 778 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, 778 is 2.
HCF(556, 778) = 2
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 556, 778 is 2.
Step 1: Since 778 > 556, we apply the division lemma to 778 and 556, to get
778 = 556 x 1 + 222
Step 2: Since the reminder 556 ≠ 0, we apply division lemma to 222 and 556, to get
556 = 222 x 2 + 112
Step 3: We consider the new divisor 222 and the new remainder 112, and apply the division lemma to get
222 = 112 x 1 + 110
We consider the new divisor 112 and the new remainder 110,and apply the division lemma to get
112 = 110 x 1 + 2
We consider the new divisor 110 and the new remainder 2,and apply the division lemma to get
110 = 2 x 55 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 556 and 778 is 2
Notice that 2 = HCF(110,2) = HCF(112,110) = HCF(222,112) = HCF(556,222) = HCF(778,556) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?
Answer: Euclid's Division Algorithm is a technique to compute the Highest Common Factor (HCF) of given positive integers.
2. what is the HCF of 556, 778?
Answer: HCF of 556, 778 is 2 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 556, 778 using Euclid's Algorithm?
Answer: For arbitrary numbers 556, 778 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
