HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 149, 657, 219, 740 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 149, 657, 219, 740 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 149, 657, 219, 740 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 149, 657, 219, 740 is 1.
HCF(149, 657, 219, 740) = 1
HCF of 149, 657, 219, 740 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 149, 657, 219, 740 is 1.
Highest Common Factor of 149,657,219,740 is 1
Step 1: Since 657 > 149, we apply the division lemma to 657 and 149, to get
657 = 149 x 4 + 61
Step 2: Since the reminder 149 ≠ 0, we apply division lemma to 61 and 149, to get
149 = 61 x 2 + 27
Step 3: We consider the new divisor 61 and the new remainder 27, and apply the division lemma to get
61 = 27 x 2 + 7
We consider the new divisor 27 and the new remainder 7,and apply the division lemma to get
27 = 7 x 3 + 6
We consider the new divisor 7 and the new remainder 6,and apply the division lemma to get
7 = 6 x 1 + 1
We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 149 and 657 is 1
Notice that 1 = HCF(6,1) = HCF(7,6) = HCF(27,7) = HCF(61,27) = HCF(149,61) = HCF(657,149) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 219 > 1, we apply the division lemma to 219 and 1, to get
219 = 1 x 219 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 219 is 1
Notice that 1 = HCF(219,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 740 > 1, we apply the division lemma to 740 and 1, to get
740 = 1 x 740 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 740 is 1
Notice that 1 = HCF(740,1) .
