HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 537, 820, 989, 726 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 537, 820, 989, 726 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 537, 820, 989, 726 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 537, 820, 989, 726 is 1.
HCF(537, 820, 989, 726) = 1
HCF of 537, 820, 989, 726 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 537, 820, 989, 726 is 1.
Highest Common Factor of 537,820,989,726 is 1
Step 1: Since 820 > 537, we apply the division lemma to 820 and 537, to get
820 = 537 x 1 + 283
Step 2: Since the reminder 537 ≠ 0, we apply division lemma to 283 and 537, to get
537 = 283 x 1 + 254
Step 3: We consider the new divisor 283 and the new remainder 254, and apply the division lemma to get
283 = 254 x 1 + 29
We consider the new divisor 254 and the new remainder 29,and apply the division lemma to get
254 = 29 x 8 + 22
We consider the new divisor 29 and the new remainder 22,and apply the division lemma to get
29 = 22 x 1 + 7
We consider the new divisor 22 and the new remainder 7,and apply the division lemma to get
22 = 7 x 3 + 1
We consider the new divisor 7 and the new remainder 1,and apply the division lemma to get
7 = 1 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 537 and 820 is 1
Notice that 1 = HCF(7,1) = HCF(22,7) = HCF(29,22) = HCF(254,29) = HCF(283,254) = HCF(537,283) = HCF(820,537) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 989 > 1, we apply the division lemma to 989 and 1, to get
989 = 1 x 989 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 989 is 1
Notice that 1 = HCF(989,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 726 > 1, we apply the division lemma to 726 and 1, to get
726 = 1 x 726 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 726 is 1
Notice that 1 = HCF(726,1) .
