HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 787, 412, 863, 985 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 787, 412, 863, 985 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 787, 412, 863, 985 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 787, 412, 863, 985 is 1.
HCF(787, 412, 863, 985) = 1
HCF of 787, 412, 863, 985 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 787, 412, 863, 985 is 1.
Highest Common Factor of 787,412,863,985 is 1
Step 1: Since 787 > 412, we apply the division lemma to 787 and 412, to get
787 = 412 x 1 + 375
Step 2: Since the reminder 412 ≠ 0, we apply division lemma to 375 and 412, to get
412 = 375 x 1 + 37
Step 3: We consider the new divisor 375 and the new remainder 37, and apply the division lemma to get
375 = 37 x 10 + 5
We consider the new divisor 37 and the new remainder 5,and apply the division lemma to get
37 = 5 x 7 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 787 and 412 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(37,5) = HCF(375,37) = HCF(412,375) = HCF(787,412) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 863 > 1, we apply the division lemma to 863 and 1, to get
863 = 1 x 863 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 863 is 1
Notice that 1 = HCF(863,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 985 > 1, we apply the division lemma to 985 and 1, to get
985 = 1 x 985 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 985 is 1
Notice that 1 = HCF(985,1) .
