HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 980, 690, 756, 899 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 980, 690, 756, 899 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 980, 690, 756, 899 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 980, 690, 756, 899 is 1.
HCF(980, 690, 756, 899) = 1
HCF of 980, 690, 756, 899 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 980, 690, 756, 899 is 1.
Highest Common Factor of 980,690,756,899 is 1
Step 1: Since 980 > 690, we apply the division lemma to 980 and 690, to get
980 = 690 x 1 + 290
Step 2: Since the reminder 690 ≠ 0, we apply division lemma to 290 and 690, to get
690 = 290 x 2 + 110
Step 3: We consider the new divisor 290 and the new remainder 110, and apply the division lemma to get
290 = 110 x 2 + 70
We consider the new divisor 110 and the new remainder 70,and apply the division lemma to get
110 = 70 x 1 + 40
We consider the new divisor 70 and the new remainder 40,and apply the division lemma to get
70 = 40 x 1 + 30
We consider the new divisor 40 and the new remainder 30,and apply the division lemma to get
40 = 30 x 1 + 10
We consider the new divisor 30 and the new remainder 10,and apply the division lemma to get
30 = 10 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 10, the HCF of 980 and 690 is 10
Notice that 10 = HCF(30,10) = HCF(40,30) = HCF(70,40) = HCF(110,70) = HCF(290,110) = HCF(690,290) = HCF(980,690) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 756 > 10, we apply the division lemma to 756 and 10, to get
756 = 10 x 75 + 6
Step 2: Since the reminder 10 ≠ 0, we apply division lemma to 6 and 10, to get
10 = 6 x 1 + 4
Step 3: We consider the new divisor 6 and the new remainder 4, and apply the division lemma to get
6 = 4 x 1 + 2
We consider the new divisor 4 and the new remainder 2, and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 10 and 756 is 2
Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(10,6) = HCF(756,10) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 899 > 2, we apply the division lemma to 899 and 2, to get
899 = 2 x 449 + 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 899 is 1
Notice that 1 = HCF(2,1) = HCF(899,2) .
