Given numbers are 784, 253, 821, 477
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(784, 253) = 198352
GCD(784, 253) = ( 784 x 253 ) / 198352
= 784 / 253
= 784
Step2:
LCM(1, 821) = 821
GCD(1, 821) = ( 1 x 821 ) / 821
= 1 / 821
= 1
Step3:
LCM(1, 477) = 477
GCD(1, 477) = ( 1 x 477 ) / 477
= 1 / 477
= 1
So, Greatest Common Divisor of 784, 253, 821, 477 is 1
