HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 615, 888, 666 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 615, 888, 666 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 615, 888, 666 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 615, 888, 666 is 3.
HCF(615, 888, 666) = 3
HCF of 615, 888, 666 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 615, 888, 666 is 3.
Highest Common Factor of 615,888,666 is 3
Step 1: Since 888 > 615, we apply the division lemma to 888 and 615, to get
888 = 615 x 1 + 273
Step 2: Since the reminder 615 ≠ 0, we apply division lemma to 273 and 615, to get
615 = 273 x 2 + 69
Step 3: We consider the new divisor 273 and the new remainder 69, and apply the division lemma to get
273 = 69 x 3 + 66
We consider the new divisor 69 and the new remainder 66,and apply the division lemma to get
69 = 66 x 1 + 3
We consider the new divisor 66 and the new remainder 3,and apply the division lemma to get
66 = 3 x 22 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 615 and 888 is 3
Notice that 3 = HCF(66,3) = HCF(69,66) = HCF(273,69) = HCF(615,273) = HCF(888,615) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 666 > 3, we apply the division lemma to 666 and 3, to get
666 = 3 x 222 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 666 is 3
Notice that 3 = HCF(666,3) .
