Given numbers are 428, 951, 647, 435
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(428, 951) = 407028
GCD(428, 951) = ( 428 x 951 ) / 407028
= 428 / 951
= 428
Step2:
LCM(1, 647) = 647
GCD(1, 647) = ( 1 x 647 ) / 647
= 1 / 647
= 1
Step3:
LCM(1, 435) = 435
GCD(1, 435) = ( 1 x 435 ) / 435
= 1 / 435
= 1
So, Greatest Common Divisor of 428, 951, 647, 435 is 1
