Given numbers are 142, 647, 666, 545
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(142, 647) = 91874
GCD(142, 647) = ( 142 x 647 ) / 91874
= 142 / 647
= 142
Step2:
LCM(1, 666) = 666
GCD(1, 666) = ( 1 x 666 ) / 666
= 1 / 666
= 1
Step3:
LCM(1, 545) = 545
GCD(1, 545) = ( 1 x 545 ) / 545
= 1 / 545
= 1
So, Greatest Common Divisor of 142, 647, 666, 545 is 1
