HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 755, 430, 437, 791 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 755, 430, 437, 791 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 755, 430, 437, 791 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 755, 430, 437, 791 is 1.
HCF(755, 430, 437, 791) = 1
HCF of 755, 430, 437, 791 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 755, 430, 437, 791 is 1.
Highest Common Factor of 755,430,437,791 is 1
Step 1: Since 755 > 430, we apply the division lemma to 755 and 430, to get
755 = 430 x 1 + 325
Step 2: Since the reminder 430 ≠ 0, we apply division lemma to 325 and 430, to get
430 = 325 x 1 + 105
Step 3: We consider the new divisor 325 and the new remainder 105, and apply the division lemma to get
325 = 105 x 3 + 10
We consider the new divisor 105 and the new remainder 10,and apply the division lemma to get
105 = 10 x 10 + 5
We consider the new divisor 10 and the new remainder 5,and apply the division lemma to get
10 = 5 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 755 and 430 is 5
Notice that 5 = HCF(10,5) = HCF(105,10) = HCF(325,105) = HCF(430,325) = HCF(755,430) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 437 > 5, we apply the division lemma to 437 and 5, to get
437 = 5 x 87 + 2
Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 2 and 5, to get
5 = 2 x 2 + 1
Step 3: 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 5 and 437 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(437,5) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 791 > 1, we apply the division lemma to 791 and 1, to get
791 = 1 x 791 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 791 is 1
Notice that 1 = HCF(791,1) .
