Prime factors of 142 are 2 x 71
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 450, 771, 545, 142
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(450, 771) = 115650
GCD(450, 771) = ( 450 x 771 ) / 115650
= 450 / 771
= 450
Step2:
LCM(3, 545) = 1635
GCD(3, 545) = ( 3 x 545 ) / 1635
= 3 / 545
= 3
Step3:
LCM(1, 142) = 142
GCD(1, 142) = ( 1 x 142 ) / 142
= 1 / 142
= 1
So, Greatest Common Divisor of 450, 771, 545, 142 is 1
