HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 754, 340, 980, 55 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 754, 340, 980, 55 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 754, 340, 980, 55 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 754, 340, 980, 55 is 1.
HCF(754, 340, 980, 55) = 1
HCF of 754, 340, 980, 55 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 754, 340, 980, 55 is 1.
Highest Common Factor of 754,340,980,55 is 1
Step 1: Since 754 > 340, we apply the division lemma to 754 and 340, to get
754 = 340 x 2 + 74
Step 2: Since the reminder 340 ≠ 0, we apply division lemma to 74 and 340, to get
340 = 74 x 4 + 44
Step 3: We consider the new divisor 74 and the new remainder 44, and apply the division lemma to get
74 = 44 x 1 + 30
We consider the new divisor 44 and the new remainder 30,and apply the division lemma to get
44 = 30 x 1 + 14
We consider the new divisor 30 and the new remainder 14,and apply the division lemma to get
30 = 14 x 2 + 2
We consider the new divisor 14 and the new remainder 2,and apply the division lemma to get
14 = 2 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 754 and 340 is 2
Notice that 2 = HCF(14,2) = HCF(30,14) = HCF(44,30) = HCF(74,44) = HCF(340,74) = HCF(754,340) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 980 > 2, we apply the division lemma to 980 and 2, to get
980 = 2 x 490 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 980 is 2
Notice that 2 = HCF(980,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 55 > 2, we apply the division lemma to 55 and 2, to get
55 = 2 x 27 + 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 55 is 1
Notice that 1 = HCF(2,1) = HCF(55,2) .
