HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 197, 158, 728, 507 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 197, 158, 728, 507 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 197, 158, 728, 507 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 197, 158, 728, 507 is 1.
HCF(197, 158, 728, 507) = 1
HCF of 197, 158, 728, 507 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 197, 158, 728, 507 is 1.
Highest Common Factor of 197,158,728,507 is 1
Step 1: Since 197 > 158, we apply the division lemma to 197 and 158, to get
197 = 158 x 1 + 39
Step 2: Since the reminder 158 ≠ 0, we apply division lemma to 39 and 158, to get
158 = 39 x 4 + 2
Step 3: We consider the new divisor 39 and the new remainder 2, and apply the division lemma to get
39 = 2 x 19 + 1
We consider the new divisor 2 and the new remainder 1, and apply the division lemma 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 197 and 158 is 1
Notice that 1 = HCF(2,1) = HCF(39,2) = HCF(158,39) = HCF(197,158) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 728 > 1, we apply the division lemma to 728 and 1, to get
728 = 1 x 728 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 728 is 1
Notice that 1 = HCF(728,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 507 > 1, we apply the division lemma to 507 and 1, to get
507 = 1 x 507 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 507 is 1
Notice that 1 = HCF(507,1) .
