HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 660, 585, 93 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 660, 585, 93 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 660, 585, 93 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 660, 585, 93 is 3.
HCF(660, 585, 93) = 3
HCF of 660, 585, 93 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 660, 585, 93 is 3.
Highest Common Factor of 660,585,93 is 3
Step 1: Since 660 > 585, we apply the division lemma to 660 and 585, to get
660 = 585 x 1 + 75
Step 2: Since the reminder 585 ≠ 0, we apply division lemma to 75 and 585, to get
585 = 75 x 7 + 60
Step 3: We consider the new divisor 75 and the new remainder 60, and apply the division lemma to get
75 = 60 x 1 + 15
We consider the new divisor 60 and the new remainder 15, and apply the division lemma to get
60 = 15 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 15, the HCF of 660 and 585 is 15
Notice that 15 = HCF(60,15) = HCF(75,60) = HCF(585,75) = HCF(660,585) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 93 > 15, we apply the division lemma to 93 and 15, to get
93 = 15 x 6 + 3
Step 2: Since the reminder 15 ≠ 0, we apply division lemma to 3 and 15, to get
15 = 3 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 15 and 93 is 3
Notice that 3 = HCF(15,3) = HCF(93,15) .
