HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 357, 786, 877 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 357, 786, 877 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 357, 786, 877 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 357, 786, 877 is 1.
HCF(357, 786, 877) = 1
HCF of 357, 786, 877 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 357, 786, 877 is 1.
Highest Common Factor of 357,786,877 is 1
Step 1: Since 786 > 357, we apply the division lemma to 786 and 357, to get
786 = 357 x 2 + 72
Step 2: Since the reminder 357 ≠ 0, we apply division lemma to 72 and 357, to get
357 = 72 x 4 + 69
Step 3: We consider the new divisor 72 and the new remainder 69, and apply the division lemma to get
72 = 69 x 1 + 3
We consider the new divisor 69 and the new remainder 3, and apply the division lemma to get
69 = 3 x 23 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 357 and 786 is 3
Notice that 3 = HCF(69,3) = HCF(72,69) = HCF(357,72) = HCF(786,357) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 877 > 3, we apply the division lemma to 877 and 3, to get
877 = 3 x 292 + 1
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 3 and 877 is 1
Notice that 1 = HCF(3,1) = HCF(877,3) .
