HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 715, 858, 541, 369 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 715, 858, 541, 369 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 715, 858, 541, 369 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 715, 858, 541, 369 is 1.
HCF(715, 858, 541, 369) = 1
HCF of 715, 858, 541, 369 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 715, 858, 541, 369 is 1.
Highest Common Factor of 715,858,541,369 is 1
Step 1: Since 858 > 715, we apply the division lemma to 858 and 715, to get
858 = 715 x 1 + 143
Step 2: Since the reminder 715 ≠ 0, we apply division lemma to 143 and 715, to get
715 = 143 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 143, the HCF of 715 and 858 is 143
Notice that 143 = HCF(715,143) = HCF(858,715) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 541 > 143, we apply the division lemma to 541 and 143, to get
541 = 143 x 3 + 112
Step 2: Since the reminder 143 ≠ 0, we apply division lemma to 112 and 143, to get
143 = 112 x 1 + 31
Step 3: We consider the new divisor 112 and the new remainder 31, and apply the division lemma to get
112 = 31 x 3 + 19
We consider the new divisor 31 and the new remainder 19,and apply the division lemma to get
31 = 19 x 1 + 12
We consider the new divisor 19 and the new remainder 12,and apply the division lemma to get
19 = 12 x 1 + 7
We consider the new divisor 12 and the new remainder 7,and apply the division lemma to get
12 = 7 x 1 + 5
We consider the new divisor 7 and the new remainder 5,and apply the division lemma to get
7 = 5 x 1 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 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 143 and 541 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(7,5) = HCF(12,7) = HCF(19,12) = HCF(31,19) = HCF(112,31) = HCF(143,112) = HCF(541,143) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 369 > 1, we apply the division lemma to 369 and 1, to get
369 = 1 x 369 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 369 is 1
Notice that 1 = HCF(369,1) .
