HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 902, 418, 261, 54 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 902, 418, 261, 54 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 902, 418, 261, 54 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 902, 418, 261, 54 is 1.
HCF(902, 418, 261, 54) = 1
HCF of 902, 418, 261, 54 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 902, 418, 261, 54 is 1.
Highest Common Factor of 902,418,261,54 is 1
Step 1: Since 902 > 418, we apply the division lemma to 902 and 418, to get
902 = 418 x 2 + 66
Step 2: Since the reminder 418 ≠ 0, we apply division lemma to 66 and 418, to get
418 = 66 x 6 + 22
Step 3: We consider the new divisor 66 and the new remainder 22, and apply the division lemma to get
66 = 22 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 22, the HCF of 902 and 418 is 22
Notice that 22 = HCF(66,22) = HCF(418,66) = HCF(902,418) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 261 > 22, we apply the division lemma to 261 and 22, to get
261 = 22 x 11 + 19
Step 2: Since the reminder 22 ≠ 0, we apply division lemma to 19 and 22, to get
22 = 19 x 1 + 3
Step 3: We consider the new divisor 19 and the new remainder 3, and apply the division lemma to get
19 = 3 x 6 + 1
We consider the new divisor 3 and the new remainder 1, and apply the division lemma 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 22 and 261 is 1
Notice that 1 = HCF(3,1) = HCF(19,3) = HCF(22,19) = HCF(261,22) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 54 > 1, we apply the division lemma to 54 and 1, to get
54 = 1 x 54 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 54 is 1
Notice that 1 = HCF(54,1) .
