Given numbers are 784, 636, 549, 257
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(784, 636) = 124656
GCD(784, 636) = ( 784 x 636 ) / 124656
= 784 / 636
= 784
Step2:
LCM(4, 549) = 2196
GCD(4, 549) = ( 4 x 549 ) / 2196
= 4 / 549
= 4
Step3:
LCM(1, 257) = 257
GCD(1, 257) = ( 1 x 257 ) / 257
= 1 / 257
= 1
So, Greatest Common Divisor of 784, 636, 549, 257 is 1
