Given numbers are 642, 303, 512, 842
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(642, 303) = 64842
GCD(642, 303) = ( 642 x 303 ) / 64842
= 642 / 303
= 642
Step2:
LCM(3, 512) = 1536
GCD(3, 512) = ( 3 x 512 ) / 1536
= 3 / 512
= 3
Step3:
LCM(1, 842) = 842
GCD(1, 842) = ( 1 x 842 ) / 842
= 1 / 842
= 1
So, Greatest Common Divisor of 642, 303, 512, 842 is 1
