Given numbers are 478, 790, 757, 843
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(478, 790) = 188810
GCD(478, 790) = ( 478 x 790 ) / 188810
= 478 / 790
= 478
Step2:
LCM(2, 757) = 1514
GCD(2, 757) = ( 2 x 757 ) / 1514
= 2 / 757
= 2
Step3:
LCM(1, 843) = 843
GCD(1, 843) = ( 1 x 843 ) / 843
= 1 / 843
= 1
So, Greatest Common Divisor of 478, 790, 757, 843 is 1
