HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 90, 26, 658, 254 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 90, 26, 658, 254 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 90, 26, 658, 254 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 90, 26, 658, 254 is 2.
HCF(90, 26, 658, 254) = 2
HCF of 90, 26, 658, 254 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 90, 26, 658, 254 is 2.
Highest Common Factor of 90,26,658,254 is 2
Step 1: Since 90 > 26, we apply the division lemma to 90 and 26, to get
90 = 26 x 3 + 12
Step 2: Since the reminder 26 ≠ 0, we apply division lemma to 12 and 26, to get
26 = 12 x 2 + 2
Step 3: 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 90 and 26 is 2
Notice that 2 = HCF(12,2) = HCF(26,12) = HCF(90,26) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 658 > 2, we apply the division lemma to 658 and 2, to get
658 = 2 x 329 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 658 is 2
Notice that 2 = HCF(658,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 254 > 2, we apply the division lemma to 254 and 2, to get
254 = 2 x 127 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 254 is 2
Notice that 2 = HCF(254,2) .
