Given numbers are 660, 978, 365, 378
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(660, 978) = 107580
GCD(660, 978) = ( 660 x 978 ) / 107580
= 660 / 978
= 660
Step2:
LCM(6, 365) = 2190
GCD(6, 365) = ( 6 x 365 ) / 2190
= 6 / 365
= 6
Step3:
LCM(1, 378) = 378
GCD(1, 378) = ( 1 x 378 ) / 378
= 1 / 378
= 1
So, Greatest Common Divisor of 660, 978, 365, 378 is 1
