HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 438, 554, 546 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 438, 554, 546 is 2 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 438, 554, 546 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 438, 554, 546 is 2.
HCF(438, 554, 546) = 2
HCF of 438, 554, 546 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 438, 554, 546 is 2.
Highest Common Factor of 438,554,546 is 2
Step 1: Since 554 > 438, we apply the division lemma to 554 and 438, to get
554 = 438 x 1 + 116
Step 2: Since the reminder 438 ≠ 0, we apply division lemma to 116 and 438, to get
438 = 116 x 3 + 90
Step 3: We consider the new divisor 116 and the new remainder 90, and apply the division lemma to get
116 = 90 x 1 + 26
We consider the new divisor 90 and the new remainder 26,and apply the division lemma to get
90 = 26 x 3 + 12
We consider the new divisor 26 and the new remainder 12,and apply the division lemma to get
26 = 12 x 2 + 2
We consider the new divisor 12 and the new remainder 2,and apply the division lemma to get
12 = 2 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 438 and 554 is 2
Notice that 2 = HCF(12,2) = HCF(26,12) = HCF(90,26) = HCF(116,90) = HCF(438,116) = HCF(554,438) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 546 > 2, we apply the division lemma to 546 and 2, to get
546 = 2 x 273 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 546 is 2
Notice that 2 = HCF(546,2) .
