Given numbers are 260, 688, 787, 458
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(260, 688) = 44720
GCD(260, 688) = ( 260 x 688 ) / 44720
= 260 / 688
= 260
Step2:
LCM(4, 787) = 3148
GCD(4, 787) = ( 4 x 787 ) / 3148
= 4 / 787
= 4
Step3:
LCM(1, 458) = 458
GCD(1, 458) = ( 1 x 458 ) / 458
= 1 / 458
= 1
So, Greatest Common Divisor of 260, 688, 787, 458 is 1
