Given numbers are 140, 278, 784, 615
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(140, 278) = 19460
GCD(140, 278) = ( 140 x 278 ) / 19460
= 140 / 278
= 140
Step2:
LCM(2, 784) = 784
GCD(2, 784) = ( 2 x 784 ) / 784
= 2 / 784
= 2
Step3:
LCM(2, 615) = 1230
GCD(2, 615) = ( 2 x 615 ) / 1230
= 2 / 615
= 2
So, Greatest Common Divisor of 140, 278, 784, 615 is 1
