HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 504, 918, 670 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 504, 918, 670 is 2 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 504, 918, 670 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 504, 918, 670 is 2.
HCF(504, 918, 670) = 2
HCF of 504, 918, 670 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 504, 918, 670 is 2.
Highest Common Factor of 504,918,670 is 2
Step 1: Since 918 > 504, we apply the division lemma to 918 and 504, to get
918 = 504 x 1 + 414
Step 2: Since the reminder 504 ≠ 0, we apply division lemma to 414 and 504, to get
504 = 414 x 1 + 90
Step 3: We consider the new divisor 414 and the new remainder 90, and apply the division lemma to get
414 = 90 x 4 + 54
We consider the new divisor 90 and the new remainder 54,and apply the division lemma to get
90 = 54 x 1 + 36
We consider the new divisor 54 and the new remainder 36,and apply the division lemma to get
54 = 36 x 1 + 18
We consider the new divisor 36 and the new remainder 18,and apply the division lemma to get
36 = 18 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 18, the HCF of 504 and 918 is 18
Notice that 18 = HCF(36,18) = HCF(54,36) = HCF(90,54) = HCF(414,90) = HCF(504,414) = HCF(918,504) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 670 > 18, we apply the division lemma to 670 and 18, to get
670 = 18 x 37 + 4
Step 2: Since the reminder 18 ≠ 0, we apply division lemma to 4 and 18, to get
18 = 4 x 4 + 2
Step 3: We consider the new divisor 4 and the new remainder 2, and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 18 and 670 is 2
Notice that 2 = HCF(4,2) = HCF(18,4) = HCF(670,18) .
