Given numbers are 645, 550, 413, 472
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(645, 550) = 70950
GCD(645, 550) = ( 645 x 550 ) / 70950
= 645 / 550
= 645
Step2:
LCM(5, 413) = 2065
GCD(5, 413) = ( 5 x 413 ) / 2065
= 5 / 413
= 5
Step3:
LCM(1, 472) = 472
GCD(1, 472) = ( 1 x 472 ) / 472
= 1 / 472
= 1
So, Greatest Common Divisor of 645, 550, 413, 472 is 1
