HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 985, 286, 198 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 985, 286, 198 is 1 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 985, 286, 198 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 985, 286, 198 is 1.
HCF(985, 286, 198) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 985, 286, 198 is 1.
Step 1: Since 985 > 286, we apply the division lemma to 985 and 286, to get
985 = 286 x 3 + 127
Step 2: Since the reminder 286 ≠ 0, we apply division lemma to 127 and 286, to get
286 = 127 x 2 + 32
Step 3: We consider the new divisor 127 and the new remainder 32, and apply the division lemma to get
127 = 32 x 3 + 31
We consider the new divisor 32 and the new remainder 31,and apply the division lemma to get
32 = 31 x 1 + 1
We consider the new divisor 31 and the new remainder 1,and apply the division lemma to get
31 = 1 x 31 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 985 and 286 is 1
Notice that 1 = HCF(31,1) = HCF(32,31) = HCF(127,32) = HCF(286,127) = HCF(985,286) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 198 > 1, we apply the division lemma to 198 and 1, to get
198 = 1 x 198 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 198 is 1
Notice that 1 = HCF(198,1) .
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 985, 286, 198?
Answer: HCF of 985, 286, 198 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 985, 286, 198 using Euclid's Algorithm?
Answer: For arbitrary numbers 985, 286, 198 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
