HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 99, 285, 756, 177 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 99, 285, 756, 177 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 99, 285, 756, 177 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 99, 285, 756, 177 is 3.
HCF(99, 285, 756, 177) = 3
HCF of 99, 285, 756, 177 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 99, 285, 756, 177 is 3.
Highest Common Factor of 99,285,756,177 is 3
Step 1: Since 285 > 99, we apply the division lemma to 285 and 99, to get
285 = 99 x 2 + 87
Step 2: Since the reminder 99 ≠ 0, we apply division lemma to 87 and 99, to get
99 = 87 x 1 + 12
Step 3: We consider the new divisor 87 and the new remainder 12, and apply the division lemma to get
87 = 12 x 7 + 3
We consider the new divisor 12 and the new remainder 3, and apply the division lemma to get
12 = 3 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 99 and 285 is 3
Notice that 3 = HCF(12,3) = HCF(87,12) = HCF(99,87) = HCF(285,99) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 756 > 3, we apply the division lemma to 756 and 3, to get
756 = 3 x 252 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 756 is 3
Notice that 3 = HCF(756,3) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 177 > 3, we apply the division lemma to 177 and 3, to get
177 = 3 x 59 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 177 is 3
Notice that 3 = HCF(177,3) .
