HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 653, 417, 732, 478 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 653, 417, 732, 478 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 653, 417, 732, 478 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 653, 417, 732, 478 is 1.
HCF(653, 417, 732, 478) = 1
HCF of 653, 417, 732, 478 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 653, 417, 732, 478 is 1.
Highest Common Factor of 653,417,732,478 is 1
Step 1: Since 653 > 417, we apply the division lemma to 653 and 417, to get
653 = 417 x 1 + 236
Step 2: Since the reminder 417 ≠ 0, we apply division lemma to 236 and 417, to get
417 = 236 x 1 + 181
Step 3: We consider the new divisor 236 and the new remainder 181, and apply the division lemma to get
236 = 181 x 1 + 55
We consider the new divisor 181 and the new remainder 55,and apply the division lemma to get
181 = 55 x 3 + 16
We consider the new divisor 55 and the new remainder 16,and apply the division lemma to get
55 = 16 x 3 + 7
We consider the new divisor 16 and the new remainder 7,and apply the division lemma to get
16 = 7 x 2 + 2
We consider the new divisor 7 and the new remainder 2,and apply the division lemma to get
7 = 2 x 3 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 653 and 417 is 1
Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(16,7) = HCF(55,16) = HCF(181,55) = HCF(236,181) = HCF(417,236) = HCF(653,417) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 732 > 1, we apply the division lemma to 732 and 1, to get
732 = 1 x 732 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 732 is 1
Notice that 1 = HCF(732,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 478 > 1, we apply the division lemma to 478 and 1, to get
478 = 1 x 478 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 478 is 1
Notice that 1 = HCF(478,1) .
