HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 153, 240, 828 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 153, 240, 828 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 153, 240, 828 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 153, 240, 828 is 3.
HCF(153, 240, 828) = 3
HCF of 153, 240, 828 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 153, 240, 828 is 3.
Highest Common Factor of 153,240,828 is 3
Step 1: Since 240 > 153, we apply the division lemma to 240 and 153, to get
240 = 153 x 1 + 87
Step 2: Since the reminder 153 ≠ 0, we apply division lemma to 87 and 153, to get
153 = 87 x 1 + 66
Step 3: We consider the new divisor 87 and the new remainder 66, and apply the division lemma to get
87 = 66 x 1 + 21
We consider the new divisor 66 and the new remainder 21,and apply the division lemma to get
66 = 21 x 3 + 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 153 and 240 is 3
Notice that 3 = HCF(21,3) = HCF(66,21) = HCF(87,66) = HCF(153,87) = HCF(240,153) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 828 > 3, we apply the division lemma to 828 and 3, to get
828 = 3 x 276 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 828 is 3
Notice that 3 = HCF(828,3) .
