HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 279, 987 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 279, 987 is 3 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 279, 987 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 279, 987 is 3.
HCF(279, 987) = 3
HCF of 279, 987 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 279, 987 is 3.
Highest Common Factor of 279,987 is 3
Step 1: Since 987 > 279, we apply the division lemma to 987 and 279, to get
987 = 279 x 3 + 150
Step 2: Since the reminder 279 ≠ 0, we apply division lemma to 150 and 279, to get
279 = 150 x 1 + 129
Step 3: We consider the new divisor 150 and the new remainder 129, and apply the division lemma to get
150 = 129 x 1 + 21
We consider the new divisor 129 and the new remainder 21,and apply the division lemma to get
129 = 21 x 6 + 3
We consider the new divisor 21 and the new remainder 3,and apply the division lemma to get
21 = 3 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 279 and 987 is 3
Notice that 3 = HCF(21,3) = HCF(129,21) = HCF(150,129) = HCF(279,150) = HCF(987,279) .
