HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 490, 734, 348, 920 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 490, 734, 348, 920 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, 734, 348, 920 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, 734, 348, 920 is 2.
HCF(490, 734, 348, 920) = 2
HCF of 490, 734, 348, 920 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, 734, 348, 920 is 2.
Highest Common Factor of 490,734,348,920 is 2
Step 1: Since 734 > 490, we apply the division lemma to 734 and 490, to get
734 = 490 x 1 + 244
Step 2: Since the reminder 490 ≠ 0, we apply division lemma to 244 and 490, to get
490 = 244 x 2 + 2
Step 3: We consider the new divisor 244 and the new remainder 2, and apply the division lemma to get
244 = 2 x 122 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 490 and 734 is 2
Notice that 2 = HCF(244,2) = HCF(490,244) = HCF(734,490) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 348 > 2, we apply the division lemma to 348 and 2, to get
348 = 2 x 174 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 348 is 2
Notice that 2 = HCF(348,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 920 > 2, we apply the division lemma to 920 and 2, to get
920 = 2 x 460 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 920 is 2
Notice that 2 = HCF(920,2) .
