HCF and LCM of 60 and 1800pls can send me the ans ​

Answer»

GCF = 60

for the values 60, 1800

Solution by Factorization:

The factors of 60 are: 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60

The factors of 1800 are: 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 18, 20, 24, 25, 30, 36, 40, 45, 50, 60, 72, 75, 90, 100, 120, 150, 180, 200, 225, 300, 360, 450, 600, 900, 1800

Then the greatest common factor is 60.

You can also find the GCF using

Prime Factorization or Euclid's Algorithm.

The LCM of numbers is the smallest number that is divisible by all given numbers.

Find some multiples of each number.

Multiples of 60:

60,120,180,240,300,360,420,480,540,600,660,720,780,840,900,960,1020,1080,1140,1200,1260,1320,1380,1440,1500,1560,1620,1680,1740,1800,1860,1920,1980

Multiples of 1800:

1800,3600,5400,7200,9000

The smallest common (all numbers share it) multiple is highlighted.

Thus, LCM(60,1800)=1800

LCM = 1800
