GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(642, 940) = 301740
GCD(642, 940) = ( 642 x 940 ) / 301740
= 642 / 940
= 642
Step2:
LCM(2, 242) = 242
GCD(2, 242) = ( 2 x 242 ) / 242
= 2 / 242
= 2
Step3:
LCM(2, 504) = 504
GCD(2, 504) = ( 2 x 504 ) / 504
= 2 / 504
= 2
So, Greatest Common Divisor of 642, 940, 242, 504 is 2
