HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 915, 564, 825 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 915, 564, 825 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 915, 564, 825 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 915, 564, 825 is 3.
HCF(915, 564, 825) = 3
HCF of 915, 564, 825 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 915, 564, 825 is 3.
Highest Common Factor of 915,564,825 is 3
Step 1: Since 915 > 564, we apply the division lemma to 915 and 564, to get
915 = 564 x 1 + 351
Step 2: Since the reminder 564 ≠ 0, we apply division lemma to 351 and 564, to get
564 = 351 x 1 + 213
Step 3: We consider the new divisor 351 and the new remainder 213, and apply the division lemma to get
351 = 213 x 1 + 138
We consider the new divisor 213 and the new remainder 138,and apply the division lemma to get
213 = 138 x 1 + 75
We consider the new divisor 138 and the new remainder 75,and apply the division lemma to get
138 = 75 x 1 + 63
We consider the new divisor 75 and the new remainder 63,and apply the division lemma to get
75 = 63 x 1 + 12
We consider the new divisor 63 and the new remainder 12,and apply the division lemma to get
63 = 12 x 5 + 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 915 and 564 is 3
Notice that 3 = HCF(12,3) = HCF(63,12) = HCF(75,63) = HCF(138,75) = HCF(213,138) = HCF(351,213) = HCF(564,351) = HCF(915,564) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 825 > 3, we apply the division lemma to 825 and 3, to get
825 = 3 x 275 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 825 is 3
Notice that 3 = HCF(825,3) .
