Given numbers are 645, 306, 372, 370
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(645, 306) = 65790
GCD(645, 306) = ( 645 x 306 ) / 65790
= 645 / 306
= 645
Step2:
LCM(3, 372) = 372
GCD(3, 372) = ( 3 x 372 ) / 372
= 3 / 372
= 3
Step3:
LCM(3, 370) = 1110
GCD(3, 370) = ( 3 x 370 ) / 1110
= 3 / 370
= 3
So, Greatest Common Divisor of 645, 306, 372, 370 is 1
