HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 619, 128, 357, 739 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 619, 128, 357, 739 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 619, 128, 357, 739 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 619, 128, 357, 739 is 1.
HCF(619, 128, 357, 739) = 1
HCF of 619, 128, 357, 739 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 619, 128, 357, 739 is 1.
Highest Common Factor of 619,128,357,739 is 1
Step 1: Since 619 > 128, we apply the division lemma to 619 and 128, to get
619 = 128 x 4 + 107
Step 2: Since the reminder 128 ≠ 0, we apply division lemma to 107 and 128, to get
128 = 107 x 1 + 21
Step 3: We consider the new divisor 107 and the new remainder 21, and apply the division lemma to get
107 = 21 x 5 + 2
We consider the new divisor 21 and the new remainder 2,and apply the division lemma to get
21 = 2 x 10 + 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 619 and 128 is 1
Notice that 1 = HCF(2,1) = HCF(21,2) = HCF(107,21) = HCF(128,107) = HCF(619,128) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 357 > 1, we apply the division lemma to 357 and 1, to get
357 = 1 x 357 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 357 is 1
Notice that 1 = HCF(357,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 739 > 1, we apply the division lemma to 739 and 1, to get
739 = 1 x 739 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 739 is 1
Notice that 1 = HCF(739,1) .
