UCLN(45,840,150,900)=.....
UCLN(45,840,150,900)
Ta có
45=5x32
840=23x3x5x7
150=2x3x52
900=22x32x52
Vậy UCLN(45,840,150,900)=3x5=15
UCLN(45,840,150,900)=
6300
tick mình nha mình trả lời đầu tiên
UCLN(45,840,150,900)=
ta có :
45=32 x5
840=23 x 3x5x7
150=2x3x52
900=22 x 32 x 52
=>ƯCLN[45;840;150;900]=3x5=15
UCLN(45,840,150,900)
45 = 32.5
840 = 23.3.5.7
150 = 2.3.52
900 = 22.32.52
=> ƯCLN(45, 840, 150, 900) = 3.5 = 15
ucln(45,840,150,900)
= 15
các bạn cho mình vài li-ke cho tròn 550 với
UCLN(45,840,150,900)
hỏi chơi
Ta có : 45 = 32.5
840= 23.3.5.7
150= 2.3.52
900=22.32.52
ƯCLN(45;840;150;900)=3.5=15
ƯCLN(45,840,150,900)
BCNN(150,250)
ƯCLN(45,840,150,900)
a/150=2.3.52
250=2.53
=>BCNN(150;250)=2.3.53=750
b/ 45=32.5
840=23.3.5.7
150=2.3.52
900=22.32.52
=>UCLN(45;840;150;900)=3.5=15
900 chia hêt cho 150
=> UCLN(45;840;150;900) =UCLN(45;840;150) ; UCLN( 45;150) =15 mà 840 chia hết cho 15
=> UCLN(45;840;150;900) = 15
