HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 90, 60, 864 i.e. 6 the largest integer that leaves a remainder zero for all numbers.
HCF of 90, 60, 864 is 6 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 90, 60, 864 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 90, 60, 864 is 6.
HCF(90, 60, 864) = 6
HCF of 90, 60, 864 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 90, 60, 864 is 6.
Highest Common Factor of 90,60,864 is 6
Step 1: Since 90 > 60, we apply the division lemma to 90 and 60, to get
90 = 60 x 1 + 30
Step 2: Since the reminder 60 ≠ 0, we apply division lemma to 30 and 60, to get
60 = 30 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 30, the HCF of 90 and 60 is 30
Notice that 30 = HCF(60,30) = HCF(90,60) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 864 > 30, we apply the division lemma to 864 and 30, to get
864 = 30 x 28 + 24
Step 2: Since the reminder 30 ≠ 0, we apply division lemma to 24 and 30, to get
30 = 24 x 1 + 6
Step 3: We consider the new divisor 24 and the new remainder 6, and apply the division lemma to get
24 = 6 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 30 and 864 is 6
Notice that 6 = HCF(24,6) = HCF(30,24) = HCF(864,30) .
