GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(142, 302) = 21442
GCD(142, 302) = ( 142 x 302 ) / 21442
= 142 / 302
= 142
Step2:
LCM(2, 947) = 1894
GCD(2, 947) = ( 2 x 947 ) / 1894
= 2 / 947
= 2
Step3:
LCM(1, 648) = 648
GCD(1, 648) = ( 1 x 648 ) / 648
= 1 / 648
= 1
So, Greatest Common Divisor of 142, 302, 947, 648 is 1
