Given numbers are 478, 778, 180, 783
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(478, 778) = 185942
GCD(478, 778) = ( 478 x 778 ) / 185942
= 478 / 778
= 478
Step2:
LCM(2, 180) = 180
GCD(2, 180) = ( 2 x 180 ) / 180
= 2 / 180
= 2
Step3:
LCM(2, 783) = 1566
GCD(2, 783) = ( 2 x 783 ) / 1566
= 2 / 783
= 2
So, Greatest Common Divisor of 478, 778, 180, 783 is 1
