Prime factors of 660 are 2 x 2 x 3 x 5 x 11
Prime factors of 145 are 5 x 29
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 246, 270, 660, 145
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(246, 270) = 11070
GCD(246, 270) = ( 246 x 270 ) / 11070
= 246 / 270
= 246
Step2:
LCM(6, 660) = 660
GCD(6, 660) = ( 6 x 660 ) / 660
= 6 / 660
= 6
Step3:
LCM(6, 145) = 870
GCD(6, 145) = ( 6 x 145 ) / 870
= 6 / 145
= 6
So, Greatest Common Divisor of 246, 270, 660, 145 is 1
