Given numbers are 645, 918, 907, 242
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(645, 918) = 197370
GCD(645, 918) = ( 645 x 918 ) / 197370
= 645 / 918
= 645
Step2:
LCM(3, 907) = 2721
GCD(3, 907) = ( 3 x 907 ) / 2721
= 3 / 907
= 3
Step3:
LCM(1, 242) = 242
GCD(1, 242) = ( 1 x 242 ) / 242
= 1 / 242
= 1
So, Greatest Common Divisor of 645, 918, 907, 242 is 1
