Given numbers are 784, 364, 688, 545
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(784, 364) = 10192
GCD(784, 364) = ( 784 x 364 ) / 10192
= 784 / 364
= 784
Step2:
LCM(28, 688) = 4816
GCD(28, 688) = ( 28 x 688 ) / 4816
= 28 / 688
= 28
Step3:
LCM(4, 545) = 2180
GCD(4, 545) = ( 4 x 545 ) / 2180
= 4 / 545
= 4
So, Greatest Common Divisor of 784, 364, 688, 545 is 1
