HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 501, 654, 621 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 501, 654, 621 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 501, 654, 621 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 501, 654, 621 is 3.
HCF(501, 654, 621) = 3
HCF of 501, 654, 621 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 501, 654, 621 is 3.
Highest Common Factor of 501,654,621 is 3
Step 1: Since 654 > 501, we apply the division lemma to 654 and 501, to get
654 = 501 x 1 + 153
Step 2: Since the reminder 501 ≠ 0, we apply division lemma to 153 and 501, to get
501 = 153 x 3 + 42
Step 3: We consider the new divisor 153 and the new remainder 42, and apply the division lemma to get
153 = 42 x 3 + 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 501 and 654 is 3
Notice that 3 = HCF(12,3) = HCF(15,12) = HCF(27,15) = HCF(42,27) = HCF(153,42) = HCF(501,153) = HCF(654,501) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 621 > 3, we apply the division lemma to 621 and 3, to get
621 = 3 x 207 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 621 is 3
Notice that 3 = HCF(621,3) .
