HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 756, 531, 177, 858 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 756, 531, 177, 858 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 756, 531, 177, 858 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 756, 531, 177, 858 is 3.
HCF(756, 531, 177, 858) = 3
HCF of 756, 531, 177, 858 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 756, 531, 177, 858 is 3.
Highest Common Factor of 756,531,177,858 is 3
Step 1: Since 756 > 531, we apply the division lemma to 756 and 531, to get
756 = 531 x 1 + 225
Step 2: Since the reminder 531 ≠ 0, we apply division lemma to 225 and 531, to get
531 = 225 x 2 + 81
Step 3: We consider the new divisor 225 and the new remainder 81, and apply the division lemma to get
225 = 81 x 2 + 63
We consider the new divisor 81 and the new remainder 63,and apply the division lemma to get
81 = 63 x 1 + 18
We consider the new divisor 63 and the new remainder 18,and apply the division lemma to get
63 = 18 x 3 + 9
We consider the new divisor 18 and the new remainder 9,and apply the division lemma to get
18 = 9 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 9, the HCF of 756 and 531 is 9
Notice that 9 = HCF(18,9) = HCF(63,18) = HCF(81,63) = HCF(225,81) = HCF(531,225) = HCF(756,531) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 177 > 9, we apply the division lemma to 177 and 9, to get
177 = 9 x 19 + 6
Step 2: Since the reminder 9 ≠ 0, we apply division lemma to 6 and 9, to get
9 = 6 x 1 + 3
Step 3: We consider the new divisor 6 and the new remainder 3, and apply the division lemma to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 9 and 177 is 3
Notice that 3 = HCF(6,3) = HCF(9,6) = HCF(177,9) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 858 > 3, we apply the division lemma to 858 and 3, to get
858 = 3 x 286 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 858 is 3
Notice that 3 = HCF(858,3) .
