Given numbers are 578, 878, 718, 647
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(578, 878) = 253742
GCD(578, 878) = ( 578 x 878 ) / 253742
= 578 / 878
= 578
Step2:
LCM(2, 718) = 718
GCD(2, 718) = ( 2 x 718 ) / 718
= 2 / 718
= 2
Step3:
LCM(2, 647) = 1294
GCD(2, 647) = ( 2 x 647 ) / 1294
= 2 / 647
= 2
So, Greatest Common Divisor of 578, 878, 718, 647 is 1
