Given numbers are 478, 256, 445, 715
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(478, 256) = 61184
GCD(478, 256) = ( 478 x 256 ) / 61184
= 478 / 256
= 478
Step2:
LCM(2, 445) = 890
GCD(2, 445) = ( 2 x 445 ) / 890
= 2 / 445
= 2
Step3:
LCM(1, 715) = 715
GCD(1, 715) = ( 1 x 715 ) / 715
= 1 / 715
= 1
So, Greatest Common Divisor of 478, 256, 445, 715 is 1
