GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(784, 993) = 778512
GCD(784, 993) = ( 784 x 993 ) / 778512
= 784 / 993
= 784
Step2:
LCM(1, 980) = 980
GCD(1, 980) = ( 1 x 980 ) / 980
= 1 / 980
= 1
Step3:
LCM(1, 542) = 542
GCD(1, 542) = ( 1 x 542 ) / 542
= 1 / 542
= 1
So, Greatest Common Divisor of 784, 993, 980, 542 is 1
