Given numbers are 605, 781, 609, 658
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(605, 781) = 42955
GCD(605, 781) = ( 605 x 781 ) / 42955
= 605 / 781
= 605
Step2:
LCM(11, 609) = 6699
GCD(11, 609) = ( 11 x 609 ) / 6699
= 11 / 609
= 11
Step3:
LCM(1, 658) = 658
GCD(1, 658) = ( 1 x 658 ) / 658
= 1 / 658
= 1
So, Greatest Common Divisor of 605, 781, 609, 658 is 1
