Given numbers are 640, 242, 210, 229
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(640, 242) = 77440
GCD(640, 242) = ( 640 x 242 ) / 77440
= 640 / 242
= 640
Step2:
LCM(2, 210) = 210
GCD(2, 210) = ( 2 x 210 ) / 210
= 2 / 210
= 2
Step3:
LCM(2, 229) = 458
GCD(2, 229) = ( 2 x 229 ) / 458
= 2 / 229
= 2
So, Greatest Common Divisor of 640, 242, 210, 229 is 1
