Given numbers are 415, 625, 555, 648
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(415, 625) = 51875
GCD(415, 625) = ( 415 x 625 ) / 51875
= 415 / 625
= 415
Step2:
LCM(5, 555) = 555
GCD(5, 555) = ( 5 x 555 ) / 555
= 5 / 555
= 5
Step3:
LCM(5, 648) = 3240
GCD(5, 648) = ( 5 x 648 ) / 3240
= 5 / 648
= 5
So, Greatest Common Divisor of 415, 625, 555, 648 is 1
