Given numbers are 356, 578, 265, 989
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(356, 578) = 102884
GCD(356, 578) = ( 356 x 578 ) / 102884
= 356 / 578
= 356
Step2:
LCM(2, 265) = 530
GCD(2, 265) = ( 2 x 265 ) / 530
= 2 / 265
= 2
Step3:
LCM(1, 989) = 989
GCD(1, 989) = ( 1 x 989 ) / 989
= 1 / 989
= 1
So, Greatest Common Divisor of 356, 578, 265, 989 is 1
