HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 354, 478, 90, 889 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 354, 478, 90, 889 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 354, 478, 90, 889 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 354, 478, 90, 889 is 1.
HCF(354, 478, 90, 889) = 1
HCF of 354, 478, 90, 889 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 354, 478, 90, 889 is 1.
Highest Common Factor of 354,478,90,889 is 1
Step 1: Since 478 > 354, we apply the division lemma to 478 and 354, to get
478 = 354 x 1 + 124
Step 2: Since the reminder 354 ≠ 0, we apply division lemma to 124 and 354, to get
354 = 124 x 2 + 106
Step 3: We consider the new divisor 124 and the new remainder 106, and apply the division lemma to get
124 = 106 x 1 + 18
We consider the new divisor 106 and the new remainder 18,and apply the division lemma to get
106 = 18 x 5 + 16
We consider the new divisor 18 and the new remainder 16,and apply the division lemma to get
18 = 16 x 1 + 2
We consider the new divisor 16 and the new remainder 2,and apply the division lemma to get
16 = 2 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 354 and 478 is 2
Notice that 2 = HCF(16,2) = HCF(18,16) = HCF(106,18) = HCF(124,106) = HCF(354,124) = HCF(478,354) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 90 > 2, we apply the division lemma to 90 and 2, to get
90 = 2 x 45 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 90 is 2
Notice that 2 = HCF(90,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 889 > 2, we apply the division lemma to 889 and 2, to get
889 = 2 x 444 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 889 is 1
Notice that 1 = HCF(2,1) = HCF(889,2) .
