HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 433, 562, 87, 981 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 433, 562, 87, 981 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 433, 562, 87, 981 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 433, 562, 87, 981 is 1.
HCF(433, 562, 87, 981) = 1
HCF of 433, 562, 87, 981 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 433, 562, 87, 981 is 1.
Highest Common Factor of 433,562,87,981 is 1
Step 1: Since 562 > 433, we apply the division lemma to 562 and 433, to get
562 = 433 x 1 + 129
Step 2: Since the reminder 433 ≠ 0, we apply division lemma to 129 and 433, to get
433 = 129 x 3 + 46
Step 3: We consider the new divisor 129 and the new remainder 46, and apply the division lemma to get
129 = 46 x 2 + 37
We consider the new divisor 46 and the new remainder 37,and apply the division lemma to get
46 = 37 x 1 + 9
We consider the new divisor 37 and the new remainder 9,and apply the division lemma to get
37 = 9 x 4 + 1
We consider the new divisor 9 and the new remainder 1,and apply the division lemma to get
9 = 1 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 433 and 562 is 1
Notice that 1 = HCF(9,1) = HCF(37,9) = HCF(46,37) = HCF(129,46) = HCF(433,129) = HCF(562,433) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 87 > 1, we apply the division lemma to 87 and 1, to get
87 = 1 x 87 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 87 is 1
Notice that 1 = HCF(87,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 981 > 1, we apply the division lemma to 981 and 1, to get
981 = 1 x 981 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 981 is 1
Notice that 1 = HCF(981,1) .
