HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 789, 444, 287 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 789, 444, 287 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 789, 444, 287 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 789, 444, 287 is 1.
HCF(789, 444, 287) = 1
HCF of 789, 444, 287 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 789, 444, 287 is 1.
Highest Common Factor of 789,444,287 is 1
Step 1: Since 789 > 444, we apply the division lemma to 789 and 444, to get
789 = 444 x 1 + 345
Step 2: Since the reminder 444 ≠ 0, we apply division lemma to 345 and 444, to get
444 = 345 x 1 + 99
Step 3: We consider the new divisor 345 and the new remainder 99, and apply the division lemma to get
345 = 99 x 3 + 48
We consider the new divisor 99 and the new remainder 48,and apply the division lemma to get
99 = 48 x 2 + 3
We consider the new divisor 48 and the new remainder 3,and apply the division lemma to get
48 = 3 x 16 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 789 and 444 is 3
Notice that 3 = HCF(48,3) = HCF(99,48) = HCF(345,99) = HCF(444,345) = HCF(789,444) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 287 > 3, we apply the division lemma to 287 and 3, to get
287 = 3 x 95 + 2
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 2 and 3, to get
3 = 2 x 1 + 1
Step 3: 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 3 and 287 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(287,3) .
