Given numbers are 645, 412, 750, 297
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(645, 412) = 265740
GCD(645, 412) = ( 645 x 412 ) / 265740
= 645 / 412
= 645
Step2:
LCM(1, 750) = 750
GCD(1, 750) = ( 1 x 750 ) / 750
= 1 / 750
= 1
Step3:
LCM(1, 297) = 297
GCD(1, 297) = ( 1 x 297 ) / 297
= 1 / 297
= 1
So, Greatest Common Divisor of 645, 412, 750, 297 is 1
