Given numbers are 142, 406, 547, 961
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(142, 406) = 28826
GCD(142, 406) = ( 142 x 406 ) / 28826
= 142 / 406
= 142
Step2:
LCM(2, 547) = 1094
GCD(2, 547) = ( 2 x 547 ) / 1094
= 2 / 547
= 2
Step3:
LCM(1, 961) = 961
GCD(1, 961) = ( 1 x 961 ) / 961
= 1 / 961
= 1
So, Greatest Common Divisor of 142, 406, 547, 961 is 1
