HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 525, 456, 921, 18 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 525, 456, 921, 18 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 525, 456, 921, 18 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 525, 456, 921, 18 is 3.
HCF(525, 456, 921, 18) = 3
HCF of 525, 456, 921, 18 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 525, 456, 921, 18 is 3.
Highest Common Factor of 525,456,921,18 is 3
Step 1: Since 525 > 456, we apply the division lemma to 525 and 456, to get
525 = 456 x 1 + 69
Step 2: Since the reminder 456 ≠ 0, we apply division lemma to 69 and 456, to get
456 = 69 x 6 + 42
Step 3: We consider the new divisor 69 and the new remainder 42, and apply the division lemma to get
69 = 42 x 1 + 27
We consider the new divisor 42 and the new remainder 27,and apply the division lemma to get
42 = 27 x 1 + 15
We consider the new divisor 27 and the new remainder 15,and apply the division lemma to get
27 = 15 x 1 + 12
We consider the new divisor 15 and the new remainder 12,and apply the division lemma to get
15 = 12 x 1 + 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 525 and 456 is 3
Notice that 3 = HCF(12,3) = HCF(15,12) = HCF(27,15) = HCF(42,27) = HCF(69,42) = HCF(456,69) = HCF(525,456) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 921 > 3, we apply the division lemma to 921 and 3, to get
921 = 3 x 307 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 921 is 3
Notice that 3 = HCF(921,3) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 18 > 3, we apply the division lemma to 18 and 3, to get
18 = 3 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 18 is 3
Notice that 3 = HCF(18,3) .
