Factor both numbers into prime numbers.
Take each Prime number the MOST it was used in any one number.
50=2x5x5
70=2x5x7
2x5x5x7=350
Another way is to write all the multiples of each one and choose
50,100,150,200,250,300,350
70,140,210,280,350
The lowest common multiple (LCM) is: 70
560
The least common multiple of the numbers 35 and 14 is 70.
The Least Common Multiple (LCM) for 30 70 is 210.
The lowest common multiple (LCM) of 42 and 70 is 210.
The lowest common multiple (LCM) is: 70
It is infinity but the lowest common multiple of 90 and 70 is 630
The least common multiple of the numbers 70 and 98 is 490.
The Least Common Multiple (LCM) for 70 120 is 840.
The LCM is: 70
280
It is: 70
It is 70
560
The least common multiple of the numbers 35 and 14 is 70.
The LCM is: 70
The LCM is: 280
