HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 825, 456, 73 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 825, 456, 73 is 1 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 825, 456, 73 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 825, 456, 73 is 1.
HCF(825, 456, 73) = 1
HCF of 825, 456, 73 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 825, 456, 73 is 1.
Highest Common Factor of 825,456,73 is 1
Step 1: Since 825 > 456, we apply the division lemma to 825 and 456, to get
825 = 456 x 1 + 369
Step 2: Since the reminder 456 ≠ 0, we apply division lemma to 369 and 456, to get
456 = 369 x 1 + 87
Step 3: We consider the new divisor 369 and the new remainder 87, and apply the division lemma to get
369 = 87 x 4 + 21
We consider the new divisor 87 and the new remainder 21,and apply the division lemma to get
87 = 21 x 4 + 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 825 and 456 is 3
Notice that 3 = HCF(21,3) = HCF(87,21) = HCF(369,87) = HCF(456,369) = HCF(825,456) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 73 > 3, we apply the division lemma to 73 and 3, to get
73 = 3 x 24 + 1
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 3 and 73 is 1
Notice that 1 = HCF(3,1) = HCF(73,3) .
