HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 720, 501, 973, 445 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 720, 501, 973, 445 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 720, 501, 973, 445 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 720, 501, 973, 445 is 1.
HCF(720, 501, 973, 445) = 1
HCF of 720, 501, 973, 445 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 720, 501, 973, 445 is 1.
Highest Common Factor of 720,501,973,445 is 1
Step 1: Since 720 > 501, we apply the division lemma to 720 and 501, to get
720 = 501 x 1 + 219
Step 2: Since the reminder 501 ≠ 0, we apply division lemma to 219 and 501, to get
501 = 219 x 2 + 63
Step 3: We consider the new divisor 219 and the new remainder 63, and apply the division lemma to get
219 = 63 x 3 + 30
We consider the new divisor 63 and the new remainder 30,and apply the division lemma to get
63 = 30 x 2 + 3
We consider the new divisor 30 and the new remainder 3,and apply the division lemma to get
30 = 3 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 720 and 501 is 3
Notice that 3 = HCF(30,3) = HCF(63,30) = HCF(219,63) = HCF(501,219) = HCF(720,501) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 973 > 3, we apply the division lemma to 973 and 3, to get
973 = 3 x 324 + 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 973 is 1
Notice that 1 = HCF(3,1) = HCF(973,3) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 445 > 1, we apply the division lemma to 445 and 1, to get
445 = 1 x 445 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 445 is 1
Notice that 1 = HCF(445,1) .
