HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 279, 777 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 279, 777 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, 777 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, 777 is 3.
HCF(279, 777) = 3
HCF of 279, 777 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, 777 is 3.
Highest Common Factor of 279,777 is 3
Step 1: Since 777 > 279, we apply the division lemma to 777 and 279, to get
777 = 279 x 2 + 219
Step 2: Since the reminder 279 ≠ 0, we apply division lemma to 219 and 279, to get
279 = 219 x 1 + 60
Step 3: We consider the new divisor 219 and the new remainder 60, and apply the division lemma to get
219 = 60 x 3 + 39
We consider the new divisor 60 and the new remainder 39,and apply the division lemma to get
60 = 39 x 1 + 21
We consider the new divisor 39 and the new remainder 21,and apply the division lemma to get
39 = 21 x 1 + 18
We consider the new divisor 21 and the new remainder 18,and apply the division lemma to get
21 = 18 x 1 + 3
We consider the new divisor 18 and the new remainder 3,and apply the division lemma to get
18 = 3 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 279 and 777 is 3
Notice that 3 = HCF(18,3) = HCF(21,18) = HCF(39,21) = HCF(60,39) = HCF(219,60) = HCF(279,219) = HCF(777,279) .
