Given numbers are 278, 952, 648, 811
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(278, 952) = 132328
GCD(278, 952) = ( 278 x 952 ) / 132328
= 278 / 952
= 278
Step2:
LCM(2, 648) = 648
GCD(2, 648) = ( 2 x 648 ) / 648
= 2 / 648
= 2
Step3:
LCM(2, 811) = 1622
GCD(2, 811) = ( 2 x 811 ) / 1622
= 2 / 811
= 2
So, Greatest Common Divisor of 278, 952, 648, 811 is 1
