Given numbers are 155, 624, 480, 457
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(155, 624) = 96720
GCD(155, 624) = ( 155 x 624 ) / 96720
= 155 / 624
= 155
Step2:
LCM(1, 480) = 480
GCD(1, 480) = ( 1 x 480 ) / 480
= 1 / 480
= 1
Step3:
LCM(1, 457) = 457
GCD(1, 457) = ( 1 x 457 ) / 457
= 1 / 457
= 1
So, Greatest Common Divisor of 155, 624, 480, 457 is 1
