HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 490, 968, 150 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 490, 968, 150 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 490, 968, 150 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 490, 968, 150 is 2.
HCF(490, 968, 150) = 2
HCF of 490, 968, 150 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 490, 968, 150 is 2.
Highest Common Factor of 490,968,150 is 2
Step 1: Since 968 > 490, we apply the division lemma to 968 and 490, to get
968 = 490 x 1 + 478
Step 2: Since the reminder 490 ≠ 0, we apply division lemma to 478 and 490, to get
490 = 478 x 1 + 12
Step 3: We consider the new divisor 478 and the new remainder 12, and apply the division lemma to get
478 = 12 x 39 + 10
We consider the new divisor 12 and the new remainder 10,and apply the division lemma to get
12 = 10 x 1 + 2
We consider the new divisor 10 and the new remainder 2,and apply the division lemma to get
10 = 2 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 490 and 968 is 2
Notice that 2 = HCF(10,2) = HCF(12,10) = HCF(478,12) = HCF(490,478) = HCF(968,490) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 150 > 2, we apply the division lemma to 150 and 2, to get
150 = 2 x 75 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 150 is 2
Notice that 2 = HCF(150,2) .
