Given numbers are 145, 340, 921, 542
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(145, 340) = 9860
GCD(145, 340) = ( 145 x 340 ) / 9860
= 145 / 340
= 145
Step2:
LCM(5, 921) = 4605
GCD(5, 921) = ( 5 x 921 ) / 4605
= 5 / 921
= 5
Step3:
LCM(1, 542) = 542
GCD(1, 542) = ( 1 x 542 ) / 542
= 1 / 542
= 1
So, Greatest Common Divisor of 145, 340, 921, 542 is 1
